Shopping for swimwear can feel daunting and, frankly, a bit uncomfortable. From terrible dressing room lighting to trying to find a style we feel confident in…the process leaves a lot to be desired. Add to that the fact that many swimsuits are made from unsustainable materials or concerning ethics and manufacturing practices. Oof.
Why consider sustainable swimwear?
Thankfully, there are sustainable swimwear brands out there creating cute and comfortable swimsuits for all shapes and sizes of bodies. Eco-friendly materials derived from recycled fabrics not only create comfy, stretchy swimwear but also divert waste from oceans and landfills, promoting a circular fashion loop that’s much better for the planet. Some eco-friendly materials you might find in your swimsuit include plant-based polyamides and recycled poly. Sustainable swimwear brands also prioritize ethical and fair production practices, ensuring their supply chain is as sustainable as possible and that workers receive fair wages and safe working conditions.
What should you look for when shopping for sustainable bathing suits?
When shopping for sustainable bathing suits, look for fabrics made from recycled materials like ECONYL® (regenerated nylon from ocean waste and fishing nets) or Repreve® (recycled polyester from plastic bottles) — both of which reduce waste while maintaining the durability and stretch swimwear needs. While organic cotton is a great eco-friendly fabric, it’s not ideal for swimsuits because it absorbs water, takes longer to dry, and lacks the elasticity needed for a secure, long-lasting fit. That’s why most sustainable swimwear still includes polyester or elastane for stretch, quick drying, and shape retention.
To ensure ethical production, check for certifications like OEKO-TEX (ensuring fabrics are free from harmful chemicals), GRS (Global Recycled Standard), or Fair Trade labels, which indicate responsible labor practices. Also, consider brands that use low-impact dyes, water-efficient production methods, and recyclable packaging to further minimize environmental impact.
These brands prioritize sustainability and ethical manufacturing, and they make shopping online easy and, dare we say, fun. Many of the below brands also include unedited photos, real customer reviews, and wonderful support teams to help you find the perfect style and fit. From mix-and-match bikinis to one-pieces and bodysuits, you’re sure to find something for your next pool day. 🏖️

This is the second I’ve purchased in 8 years…and it gets worn several times a week in a regular old swimming pool!

We love this brand’s diverse swimwear options, like tankinis, mommy-and-me sets, and swim dresses!
Customer Review | I am quite different sizes between bust and hips but this suit is super flattering and fits well in all places.

Best For | Gender-neutral & gender-fluid swimwear

Don’t let the name fool you, TomboyX was created for “any girl or woman or person” who dresses and expresses themselves the way they please. If you’re looking to break from the itty-bitty bikini mold, the certified B Corp makes gender-neutral tanks, halter tops, and racerbacks that can be paired with shorts of varying lengths — or you can opt for a unisuit altogether. All are quick-drying, equipped with UPF sun protection, and made with OEKO-TEX certified fabrics. (And the brand’s ethics and sustainability are top-notch, too.)
Customer Review | “I bought a size up after looking at reviews. It fits perfectly. I was worried the length would be too short bc I sensitive about my thighs and didn’t want them to rub, but the length is perfect. It doesn’t give you an extra long crotch either, it goes where you need it. The zipper tucks away as well so you don’t have it swinging around or feel that it’s going to get stuck on something. The sleeves are nice and form fitted too. 10/10 would recommend.” – Melanie T. (Read all reviews.)

Size Range | XS – 5XL
Londre was born when its co-founders became obsessed with creating the highest quality bodywear with the lowest impact. Now, the brand’s best-selling one-pieces can be worn to the beach as easily as they can be paired with a blazer. But if you’re looking for something more classic (with a twist!), opt for the high-waisted bottoms and asymmetrical tops. We’ve never worn a suit quite like one from Londre — the cut and shape are so unique and we get lots of compliments on these pieces. Made in bright colors and patterns, the products are able to withstand all salt, sand, or sweat.
Customer Review | “This suit fits like a glove. Shows off my curves and is cut in such a way that you have coverage where needed and a little pop of skin that showcases my assets beautifully. The fiesta red is RED HOT 🔥💋” – Sarah P. (Read all reviews.)

For sustainable swimwear designed in the UK, Boden is our go-to. These stunning swimsuits — including tankini tops, one-pieces, and bikinis — are majority made from recycled polyester and plastics. (By this year, 100 percent of its swimwear textiles will be recycled!) You won’t need to replace your bikini after only one season either; the team promises its suits will last. The 365-day return policy (for credit) guarantees it. Boden ships globally!
Customer Review | “Great fit, fabulous fabric. Arrived promptly with efficient tracking“ – Lynn (Read all reviews.)
11. Youswim
Best For | A swimsuit you can wear forever
Sustainable Materials | OEKO-TEX certified nylon & elastane
Price Range | Separates starting at $99; one-pieces starting at $149
Size Range | US 2 – 24
Seven sizes in one? We know, but hear us out! Youswim simply doesn’t do sizes; the brand has three uniquely simple one-piece styles, and six seperates styles instead — the Aplomb, Eva, and Poise. Find the fit you love most, choose one of the vibrant colors, and pay one price across all pieces. Each sustainable swimsuit is made with European-sourced nylon, woven ethically in England and is certified Plastic Negative; the team is also diligently working on a recycled nylon fabric to use instead to maximize its sustainability.
Customer Review | “After a year of contemplating buying a suit from Youswim I finally pulled the trigger. A great investment and will be purchasing another. Form right to your body. Is flexible, comfortable and great material.” – Michalena R. (Read all reviews.)
12. Carve Designs
Best For | Surf swimwear
Sustainable Materials | Recycled polyester
Price Range | Separates starting at $48; one-pieces starting at $84
Size Range | XS – XL
Carve Designs was born from a love of adventure and a need for swimwear that actually keeps up, no matter the elements. What started as a surf trip turned into a full-blown beach lifestyle brand dedicated to effortless, feminine styles that fit women of all shapes and sizes. Sustainability is at the heart of it all — 95% of their collection is made from recycled, upcycled, or eco-friendly materials, including their signature recycled swim fabric, which repurposes five plastic bottles per suit. Plus, we love how easy it is to filter your swimsuit search by coverage, activity, fit, support, torso length, and more, so you can find the perfect suit for your next adventure!
Customer Review | “Love this suit. Very feminine and keeps the girls in place. Also doesn’t ride up in the bottom – stays put there as well.” – Robyn (Read all reviews.)
13. Kitty and Vibe
Best For | Swimwear catered to different booty sizes
Sustainable Materials | Recycled polyester
Price Range | Separates starting at $72; one-pieces starting at $138
Size Range | XS – 6X
Kitty and Vibe is redefining the way bikinis fit by moving beyond traditional sizing. Unlike most brands that base their designs on a single size, the brand fit-tests across four size stages to ensure a better, more flattering swimsuit for all body types. It is also the only brand offering bikini bottoms tailored to booty size, preventing issues of excess or insufficient fabric. Crafted from buttery-soft, SPF 50+ recycled fabric from Colombia, these swimsuits are quick-drying, snag-resistant, and designed to maintain vibrant colors over time.
Customer Review | “I love this top! It is so cute yet supportive of the girls, which is a rare to find in a bikini top! The pattern Isla is soo much fun, so flattering, playful and bright! Highly recommended for bigger chested girlies” – Rebecca (Read all reviews.)
14. Wolven
Best For | Patterned swimsuits
Sustainable Materials | Recycled PET
Price Range | Separates starting at $52, one-pieces starting at $128
Size Range | XS – XL
Wolven’s founder Kiran Jade draws from her South Asian family’s background for its gorgeous patterns and textiles. Wolven’s swimwear for example — made up of one-pieces and bikini sets — includes mandalas and henna-inspired designs. Each piece is made from 80+ percent recycled plastic bottles with a bit of spandex for extra stretch, so you can run freely across the shores or cannonball into the pool. The fact that many of Wolven’s suits are reversible is so fun to experiment with. (But heads up: If you need structured support, cups, or additional lining, this might not be the brand for you!) Wolven orders are carbon-neutral, give back to environmental causes, and are sent in either recycled or biodegradable packaging.
Customer Review | “I absolutely adore these tops from Wolven! Can be worn as a low impact sports bra or for swim and the convertible factor is such a bonus!” – Brittney R. (Read all reviews.)
15. Galamaar
Best For | Recycled nylon and retro prints
Sustainable Materials | Recycled ECONYL®
Price Range | Separates starting at $118, one-pieces starting at $248
Size Range | XS – XL
At Galamaar, waste-to-wear is the name of the game. These beautiful suits are made in part using recycled Econyl®, a fabric derived of nylon from trashed fishing nets that account for nearly 10% of ocean pollution. Not only is the material sustainable, but it’s also made to last: Following the brand’s care guidelines, your Galamaar suits can last a lifetime. Made in a small, family-owned and operated fair-wage manufacturer in LA, you can feel good about this swimwear that is ethically made, eco-friendly, and extremely chic.
