Oana Romaneiro was inspired to create a quality, eco-friendly swimwear line after one trip where her pricy bikini broke. The model-turned-founder had previously gotten a glimpse of the fashion industry’s lack of sustainability. “[Sustainability] is really important in fashion because the rate at which fashion is being delivered [and] consumed is growing exponentially every year and it’s becoming damaging to the environment as well as our own psychological wellbeing,” says Romaneiro.

She made it her mission to create sophisticated swimwear that protects the environment. According to its site, every part of Kōraru’s swimwear is made with compassion toward the earth starting with the fabric. Each suit is made from Econyl, a regenerated nylon made from a variety of waste sources. Each bikini is wrapped in a Paptic Tringa envelope, a type of cellulose that’s made with wood fibers sourced from sustainably-managed forests. For packaging, the box linings are made from Shiro Alga Carta, a type of algae that is taken from areas where algae overgrowth is a threat to the ocean's fragile ecosystem. “As consumers, we make better choices when we are educated on what we buy. The more we know about the world around us and about ourselves, the less we need,” says Romaneiro. 



Bondi Born

From its practices to its donations, the Aussie brand Bondi Born boasts a lofty list of eco-friendly initiatives. Based and made locally in Sydney, co-founders Dale McCarthy and Creative Director Karla Clarke “believe that running a business is not just about profit,” says Bondi Born’s website. “In our own small way, we can be a force for good.”

The OEKO-TEX Certified brand does so with the use of several conscious fabrics, primarily Sculpteur which is made from recycled fabrics and emits a 10th of the carbon footprint that typical virgin polyester thread does. Its other patented fabrics include Singuleur and Embodee, both of which hold five environment-friendly certifications. Bondi Born is also certified by B Corporation, which indicates that the brand is held to high standards in a multitude of ways—not just by its fabrics. The predominantly female-operated brand has earned this badge through Codes of Conduct, sustainably certified fabrics, employee care through compensation and benefits, banned plastic packaging, and minimizing low energy and water use in its factories. Bondi Born also works with One Tree Planted (plants a tree for every order) and 1% For The Planet, which donates one percent of revenue to eco-conscious non-profits.




Founded in October 2021, Nua was created by Ananda Saba, who wanted to build a brand that was ethically produced and made with love in the U.S. Each Nua suit is ethically produced in Los Angeles and a majority are made from recycled fabrics such as fibers repurposed from water bottles. The brand's styles are designed by Brazilian artisans who work exclusively for Nua. "Most of the packaging is made from recycled plastic materials and some, like our tape, sticker, and wrapping paper are made out of compostable rice paper,” shares its founder. In addition, Nua donates 10 to 15 percent of sales to the Brazil Foundation’s Amazon fund which provides emergency and long-term support to the people of the Brazilian Amazon. “We aren’t quite 100% [sustainable] yet, but [we’re] working on it as we grow,” says Saba.




Founded by Ainsley Rose and Hannah Todd, Londre’s mission statement is to create “high-quality garments with the lowest possible impact”—and it's doing so in a number of ways.  All of Londre’s swimsuits are a blend of chitosante (naturally non-toxic discarded shells from shellfish) and recycled plastic bottles sourced from an OEKO-Tex Standard 100-certified factory. ​All of its dyes are free from harmful chemicals and its water is safely reused in the production process. Londre guarantees long-lasting pieces and offers reimbursement for repairs on any swimsuit in its first year. With fully recyclable and compostable packaging, the brand also plants coral for every order over $150, planting three coral reefs so far. Its most recent release is made of beans. The bio-based textile is a sustainable source made from castor beans with a relatively low environmental impact. The castor plant fibers are blended with a bio-based polyamide called EVO by Fulgar, which is completely renewable, fast drying, thermal, lightweight, and roughly a quarter of the environmental impact of standard polyamide.



Waikiki The Label

Established in 2018, this high-end boutique swim and athleisure brand uses Vita fabrics by Carvico, an Italian textile company. This ecological fabric is made from Econyl, a 100% regenerated polyamide (nylon) from pre- and post-consumer materials. It is resistant to suit-degrading factors such as chlorine and sun lotions or oils. Each printed suit uses non-toxic ecological inks, preventing harmful dye run-off into the oceans. All packaging including gift bags, hygiene stickers, and hand tags is manufactured from recycled materials. 

Waikiki’s factories emphasize transparency and equality prioritizing more-than-satisfactory working conditions. Its factory staff is paid three times the minimum wage standard and provides jobs for Bali residents, supporting the local economy. The brand's production works with the R.O.L.E. Foundation (a zero-waste facility and end environmental development program) where “each bikini our customers buy, we donate €1 to the ocean clean up project.” The partnership also regulates staff sustainability education, monitors waste management, and has removed the use of plastic water bottles in their facilities completely.




You may know this Aussie brand for its bold prints inspired by exotic locations—and its swimwear is just as recognizable. The brand's suits are made of Econyl, a sustainable Italian textile made from recycled nylon and regenerated materials such as waste found in the ocean. Its boardshorts for men are also all made with recycled polyester fibers made from post-consumer waste like plastic bottles and is approved by the Global Recycled Standard.

Founder Camilla Franks has gone to great lengths to guarantee safety from the ground up, from its employees to its production. As of 2022 everything used in its warehouse and boutiques is completely recyclable. Camilla chose to use digital printing for its fun patterns which greatly reduces the use of water (by 90% compared to typical production processes) and energy. Its textile mills have also received Standard 100 certification by OEKO-TEX® and all of Camilla's suppliers comply with an Animal Welfare Policy. For its staff, the brand follows a code of conduct outlined by the Ethical Trading Initiative (ETI) Base Code, offers education services through the Australian Literacy & Numeracy Foundation, and works respectfully with Aboriginal artists for capsule collections that are invested back into the community. For every online order, shoppers donate $1 to a charity of their choice out of The Hunger Project, National Breast Cancer Foundation, or Women's Community Shelter. Further philanthropy includes a $20,000 donation to reef conservation.



Dippin' Daisy's

Founded in 2015, Dippin’ Daisy’s reduces their environmental footprint through “sustainable textiles, production methods and packaging.” Founder Elaine Tran set out to create an inclusive, supportive brand for women—which includes Mother Earth.  Each suit is produced in Los Angeles (where the brand is based) using recycled nylon in small batches to avoid contributing to landfill waste. Details such as hardware for the adjustable strap sliders are made of lead-free non-toxic metal, padded inserts are made of recycled foam, and elastic is repurposed from organic and natural rubber trees. Rather than using toxic dyes, the AAPI-owned brand uses digital printing, a method that saves water,  ink, and fabric in the process. The brand uses biodegradable packaging made from chemically recycled materials that break down easier in the recycle phase.  Its paper inserts are made of raw materials using renewable green energy with a minimum of thirty percent post-consumer fibers. As of April 2022, the brand began an Earth Month campaign with its second RE:PURPOSE Collection. The entire Wild Thing collection is repurposed using deadstock fabrics from past excess scraps, giving new life to previous waste. The Plant A Tree Tuesday initiative will plant one tree for every suit purchased from the RE:PURPOSE Collection each Tuesday going forward. So, jump into these planet-loving suits with a clean conscience knowing you just planted some roots.



Revel Rey

Brand owner Audrey “Rey” Swanson draws influence from her world-class travels and her architecture background to combine fashion and art through sustainable swimwear. Made in Bali, the eponymous label is an Insta-favorite among popular It girls like Brittany Xavier, Sophie Turner, and Madelaine Petsch. Luckily, you can sport its trendy styles with a clear conscience since Revel Rey is going the extra eco-mile. A majority of its fabric is made out of regenerated nylon and doesn’t contain or release any harmful substances that could be hazardous to your health or environment. Revel Rey’s Bali factory partners with a recycled thread company in Jakarta, Indonesia. Since 2019, the company has repurposed its extra textiles by spinning them into new knits for other companies to buy, successfully eliminating any fabric waste from the brand. Some scraps are even turned into matching hair ties. Garments are packaged in poly bags made from biodegradable materials (that won’t spend the rest of eternity in a landfill) and recycled cardboard for mailing.



JMP The Label

Founders Juliette Porter, Jaymi Washburn, and David Kelleher are continuously innovating to help improve the state of our planet through their swimwear line, JMP The Label. Its factory, Trend Studio Bali, is predominantly female and held to the US standard of fair wages, health benefits, and labor practices such as respectful and safe working conditions for its employees. The factory also upcycles its fabric scraps that villagers repurpose for other goods like bags and dolls in local boutiques. In addition, JMP uses deadstock fabrics to repurpose its ‘kinis. Its mailers and packaging are created from a combination of low-impact resources: PBAT, a bio-based polymer, and PLA (plant materials like wheat or corn) that is completely compostable. 




Beloved for its inclusive sizing and perfected fits, the intimates brand kicked off this summer with a long-awaited swimwear line inspired by its signature bras and underwear. Cuup’s swimwear delivers water-friendly versions of its most popular silhouettes in 53 different sizes. You can even schedule a virtual appointment with Cuup’s “fit therapist” to find your perfect size. (Spoiler from someone who’s done it: I have been wearing the wrong bra size for years.) Out of its five core bras, three crowd-favorites—The Plunge, The Balconette, and The Scoop—arrive in swim with the brand’s classic sizing, which ranges from 30 to 42 (bust) and A to H (cup). For bottoms, the Tap, Highwaist, and Bikini bottoms offer light- to high-coverage options in sizes XS to XXXL. The fabric is constructed in Italy with Econyl yarn and is offered in five summer-loving shades: Seaweed (green), Lava (red), Shell (white), Earth (brown), and Black.



VDM The Label

Making clothes that “look good, feel good, and do good” is VDM’s motto, and they’re certainly following through. Its owner and creator Allanah Rosenwald has always prioritized the environment, from the great outdoors to that of her factory. “Rosenwald, works closely with our manufacturer in Indonesia, ensuring working conditions are ethical and optimal,” reads VDM The Label’s site. VDM’s packaging is made from corn starch which is 100 percent biodegradable. The brand also uses electronic invoicing, return slips, and gift cards to be as paper- and plastic-free as possible. Its solid color suits are made of DNV GL-certified Econyl (each bikini uses roughly 10 recycled plastic bottles) while its prints are made from Repreve. Repreve is also created from recycled materials like plastic bottles, but its composition holds patterns better, plus its production uses 45 percent less energy, emits over 30 percent fewer greenhouse gases and uses 20 percent less water. To seal the deal, most of its bikini separates are reversible with equally cute linings so you can truly get double the wear from a single suit. Plus, its matching cover ups are also sustainably made out of 100 percent eco-rayon, which is made of wood cellulose that has been grown in farmed forests certified by the Forest Stewardship Council.




Summersalt has become a crowd favorite for it’s emphasis on size inclusivity, specifically its best-selling one pieces, which are constantly selling out. The eco-friendly brand uses fabric consisting of 78 percent recycled polyamide crafted from post-consumer materials and nylon waste (like old fishing nets salvaged from the ocean). The compressive and durable fabric offers a UPF of 50+ (Ultraviolet Protection Factor measures the amount of radiation exposure that will reach your skin through fabric.) The rest of its fabrics include Tencel, Tencel Modal, and Cupro. Tencel is made of sustainably sourced raw wood. The fibers are certified by Oeko-Tex (a European eco-tracking label), whose Standard 100 initiative tests and confirms that the textiles contain low levels of harmful substances (like chemicals from manufacturing) and are “harmless for human health.” Tencel Modal is naturally made from Beechwood trees, so it's biodegradable and compostable—plus, it’s extra soft. Lastly, Cupro is made of what was previously the leftover waste from cotton (effectively making cotton a no-waste plant) while the water used to produce the fabric can be cleaned to reuse. Summersalt’s dyes are Oeko-Tex–certified and every order is shipped in poly bags made from recycled materials. Additionally, the brand’s shipping mailers have a double adhesive for multi-use, which reduces waste (and comes in handy for making returns). Even its promotional postcards are made from FSC-certified paper.



Tropic of C

Victoria’s Secret Angel turned brand founder Candice Swanepoel launched Tropic of C with the intent of making sustainability sexy. Starting with its fabrics, the majority of its swimsuits are made of Econyl, which gives post-consumer waste (like recycled fishing nets, industrial plastics, and fabric scraps) a stylish second life. Other suits are made from Lycra Xtra Life (which resists fading and damage from chemicals like chlorine and lotions) or Repreve (a polyester fiber made of 100 percent recycled plastic bottles). The supermodel’s brand also uses digital screen printing on Regen fabric—which is also made of recycled plastics and uses significantly less water and electricity than other popular printing methods. The fabric tags are made from recycled polyester while hang tags are made of bamboo. Items are packed in compostable garment bags and are protected with bioplastic hygienic liners (made from tree pulp). So, yes, wearing Tropic of C is as good for the planet as it looks.




Co-founders Noyes Hutchinson and Mandi Glynn founded Skatie on the idea that “sustainability encompasses more than just an environmental responsibility,” according to the brand’s site. Every piece from the West Coast brand is hand-made in Los Angeles and shipped in biodegradable packaging. “Staying local gives us the ability to ensure our production team is being treated and compensated fairly,” says Glynn. “Additionally, manufacturing in the United States cuts down on carbon emissions that are unavoidable when producing and shipping overseas.” Skatie sources its fabrics in one of two ways: fibers made of recycled materials or locally sourced, pre-existing stock from a textile marketplace. This helps keep plastics out of landfills and oceans while also preventing pollution from further textile manufacturing. The process of dying and printing on fabric can require incredibly high water consumption—plus, the run-off can contain harmful chemicals when not properly disposed of. To avoid this, the brand uses a heat process to transfer prints and colors.




Founded in October 2014 by siblings Raffaella and Stefano Raffo, Capittana is focused on sustainability and female empowerment. Originally rooted in swimwear with an expansion into activewear and loungewear, the revolutionary Latin brand uses a factory that recycles its water, uses solar panels for energy, and has tree plantations to neutralize its carbon output. Plus, the suits are created by at-risk women in Lima, Peru. “[Our suits] are a way to give back to our community, while protecting the planet,” share its founders. The retro floral of the new Teresa suit is perfectly on par with this summer’s favorite Seventies trend—and the matching Funky Flowers Sarong just might be the ultimate vacation outfit.



Jade Swim

Jade Swim founder and designer Brittany Kozerski has encapsulated the meaning of multifaceted minimalism and eco-conscious practices. The brand uses a regenerated nylon called Econyl (made of fishing nets, plastic bottles, or fabric scraps). This effectively reduces ocean waste and prolongs the life cycle of the fabric. Made in the United States, Jade is also a member of 1% For The Planet as well as the Eden Reforestation Projects, which plants one tree per sale. And if that wasn’t enough to sway you, Jade is Climate Neutral certified, which is a certification earned by companies that equalize their carbon emissions. Jade partners with this eco-saving organization by constantly submitting its supply chain for audit to ensure that it’s reducing future emissions. “Our collections are designed to be timeless and less reactive to fast-fashion fleeting trends,” the brand shares with Editorialist. “Many of our classic designs carry over seasons in order to reduce clothing waste.”



San Lorenzo

San Lorenzo was founded in beautiful Hawaii, where it continues to be designed. Its team is devoted to conserving the world's beaches and ecosystems. “We want sustainability to be a standard in this day and age—especially when it comes to fashion,” shares Lisseth Figueroa, owner and designer. “We’re the opposite of fast fashion.” How, you ask? At its start in 2009, the brand launched with a collection of organic cotton. Since then, it has produced its collections in extremely limited quantities and practiced a direct-to-consumer business model. “We've made mini collections out of deadstock, and upcycled fabrics into accessories, swim, and cute patchwork bikinis.” San Lorenzo has also partnered with The Solvay Group (a Brazil-based eco-tech company) to make every piece out of 100 percent biodegradable and recycled nylon. The yarn’s formula allows garments to decompose upon being discarded in landfills, where it can completely dissolve in three years. The fabric is soft, light, comfortable, and quick to dry, saving water. The environmentally friendly fabric even has a UPF factor of 50+ to block the skin from UVA and UVB rays. Next to thrifting, these suits are earth's best friend.




Pronounced o͞okēō, OOKIOH is inspired by the Japanese Ukiyo-e genre, which is all about traveling, female beauty, and living in the moment. This syncs with the brand’s theme; OOKIOH is mindfully creating clean swimwear that uplifts its wearers as well as the planet. Its suits are made from 100 percent regenerated materials, like recycled fishing nets—with the exception of a special collaboration with Rachel Wang. This high-end collection is completely composed of post-consumer waste (recycled nylon and recycled plastic bottles) that has been revived into timeless, minimalist designs. All the while, the pieces remain at affordable price points, ranging from $79 for separates and $158 for one-pieces. “To mitigate the damage done by fast fashion, we believe that it is critical to ensure that environment-friendly fashion is affordable,” says founder Vivek Agarwal. “Designing pieces that are stylish, trendy, and within reach of the masses is the only way to create more demand for recycling waste into fashion



Vitamin A

The Laguna beach–based brand boasts a lengthy list of sustainability efforts. The brand’s founder Amahlia Stevens patented its EcoLux fabric (a signature, sustainable weave made of superfine matte jersey) and stretch-ribbed EcoRib fabric—both of which are made from recycled nylon. Its strictly monitored factories are based in California with a dedication to fair trade, partnering with artisans for global production. A majority of Vitamin A’s patterns are digitally printed, which greatly reduces water waste (because it requires less wash and rinse cycles than the common wet-printing method). This also rids the need for screen print and coloring baths that create further waste. The list continues: Its headquarters and warehouses only uses LED bulbs (cutting its electricity demand by 90 percent) and are equipped with solar-powered fans, low-flow water fixtures, motion-sensored lighting, and 100 percent recycled, post-consumer-waste paper products. The brand’s recent launch is a low-waste, versatile collaboration with Misha Nonoo that features one of our favorite fashion gals, Amy Julliette Lefévre. The riveting Sustainable Summer Getaway capsule is dipped in summer shades of sea green, sapphire, and rust and specifically designed for “beach to après” on steamy summer nights.




From its textiles to mailers, Lokiki is firmly rooted on a mission dedicated towards sustainability—thanks to the initiatives of co-founders Jen Dwin and Jen DeLory. The brand’s core fabric is Italian-made of recycled nylon from fishing nets. Each batch is created in small quantities (to reduce the carbon footprint) in New York City. And each suit is dual-layered for a supportive fit without any bulky padding. Its shipping bags are constructed of recycled paper and printed with earth-friendly ink (as opposed to some inks that may break down into pollutant chemicals). The brand is also working towards 100 percent compostable packaging materials for shipping as well as 100 percent recycled paper handbags by the end of summer 2021. The founders also donate 4 percent of profits to clean water funds, which may help provide filtered drinking water to those in need or work to clean up ocean waste to protect our sea life.




Sanctuary’s mission statement is a call to action for greater eco-awareness. “With every new partner, Sanctuary requires that the brand focus on sustainability, give-back components and inclusivity,” says its creative director Debra Polanco. The brand specializes in jeans and has created a smart creation process to help undo the water-heavy creation process of denim. Ultimately, it also applies to its swimwear. Its three-point plan includes low-impact fibers, recycled plastics, and an advanced wash process. The brand partnered with Amerex Swim Group for its swim line, which has enabled Sanctuary’s swim to consist of 90 percent recycled materials. Fibers like linen and tencel use up to 20 times less water; non-toxic production processes reduce minimal waste and pollutants. Internally, the brand avoids plastics as a whole (from the office to photoshoots) and sources recycled paper wherever possible.




Hermoza’s main goal is to make suits that don’t require a single sacrifice—whether that’s in terms of style, fit, or investment. The brand’s care for the planet is consistent with its practices. All of its fabrics boast a high UPF; Made with a regenerated nylon fiber from pre- and post-consumer materials, its UV transmission is less than 2.5 percent when exposed to both UV and UVB light. The environmentally friendly dying and cleaning process ensures no harmful toxins or chemicals are leaked into the environment. Hermoza even insists that its suits are significantly resistant to wear and tear—even with the most intense use like water sports. The recycled fabric is durable enough to resist abrasions and chlorine as well as body lotions and oils so that nothing affects its vibrancy. All of this combined was enough to make Oprah a fan. The Genevieve was featured in O magazine and, obviously, anything Oprah-approved has to be great.



Zulu & Zephyr

With nearly a decade as one of Australia’s favorite swim brands, Zulu & Zephyr is dedicated to its long-term sustainability efforts in several ways. “Since the launch of our Econyl swimwear in 2020, we have saved 28,000 barrels of crude oil and 26,040 tons of CO2 emissions,” shares the brand in an interview with Editorialist. Econyl is a type of regenerated nylon that sells its textiles for fashion, sportswear, and swimwear. The covetable brand also partners with Healthy Seas to support marine protection and uses organic cotton. The brand is working towards plastic neutrality and donates one percent of gross annual sales to 1% For The Planet.




“Whether or not Momma was going to be sustainable was never a question for me,” says its founder Jackie Robinson, adding “it’s just the right thing to do.” The designer decided to use recycled nylon for its superior stretch and feel. “After testing hundreds of swatches on our journey to find the right fabric, we ultimately made our own custom blend for peak comfort,” says Robinson. The original fabric is 80 percent recycled nylon and 20 percent spandex. Every suit is wrapped in a biodegradable plastic, our tissue and stickers are recyclable, and our mailers can be recycled as you would grocery bags. Momma also makes donations to support One Tree Planted (which plants one tree in a US National Forest for every order purchased) and the United States Forest Service. Comfortable, multifunctional, and confidence-boosting suits are what you can expect from the inclusive brand. “We love to appeal to women of all shapes, sizes, and ethnicities and our customers really reflect that.”




Myraswim is sought after for its timeless designs and versatile hues. Sleek shapes and neutral shades (black, chocolate, vanilla and clay) are a minimalist's dream come true. “Since I started bulk manufacturing in 2014, I frequently traveled to my manufactures overseas to always ensure my garments are being constructed in a healthy environment,” says the founder, designer and owner Bianca Anstiss. Anstiss is a pro surfer so “having ethically made garments has been a long-term thing for me,” she says.  “I consider (Myraswim) 110 percent slow fashion.” The brand has since transformed its shopping experience to be fully long-lasting with reusable, multi-purpose garment bags and environmentally friendly postage materials. Lastly, its national deliveries are sent with Australia Post, which is a carbon-neutral option. Its staples like the Diego top and Aloe one piece are ideal options for mixing swimwear into your daytime wardrobe. Its terrycloth Resort line is also the perfect embodiment of trying the toweling trend.
