Our Madewell Second Wave swim collection has a built-in feel-good factor—the fabric was made using recycled material. A fresh take on a tank style in an '80s-inspired animal print, this square-neck one-piece has a built-in shelf bra, a low back and a flattering legs-for-days cut. With sizes running from 1X to 3X, it's an "everyone needs it" kinda deal. Regular fit. UPF 50 sun protection. Made from 80% pre-consumer recycled nylon/20% elastane. Do Well: This fabric is recycled from pre-consumer nylon waste like fishing nets, fabric scraps or carpet. Our swimsuits are machine washable, but we recommend hand washing as it helps keep the fabric and the shape of the suit looking newer, longer. Import. Madewell. Com only.
