UNDERSEA BIKINI is an eco-friendly swimwear label catering to those who desire a comfortable product they can feel good about wearing. Our goal is to offer a fashionable product that is consciously created and designed to last. We have a global mission to inspire women to become conscious consumers and generous towards the environment. We believe that fashion should be fair, and luxury should automatically be about sustainability.


Our collection is feminine with a sporty twist, handmade from soft, Italian fabrics derived from ECONYL® 100% REGENERATED NYLON. The premium material is resurrected by volunteer divers, recovering abandoned fishing nets and other nylon waste material from the bottom of the seas to bring them into life again in our high-quality swimwear.

Staying true to our values, all of our packages are made of recycled and sustainably sourced materials. Our hangtags are made from seed papers, that means you can plant it in your garden and watch it grow!


This season, UNDERSEA BIKINI is partnering with MANTA TRUST, a great team contributing their time and skill to conserve mobulid rays, their relatives, and their habitats, through a combination of research and education. By purchasing our RAY TOP / BOTTOM, you support their hard work with 10% of the price.

At the same time, we are partnering with the ONE TREE PLANTED organization as well to keep the surface green! Their mission is to reforest the planet while raising awareness about the importance of trees. After every single bikini you buy, they plant a tree in the ground!  


Let’s create a wave of change together & keep the ocean clean in style!
