Sold out on website Our Madewell Second Wave swim collection has a built-in feel-good factor—the polka-dot fabric was made using recycled material. And the look-good factor is no joke either: Designed with a legs-for-days effect, this one-piece has a sporty straight neckline and a flattering cutout riiiiiiight above the belly button. With sizes running from XXS to XXL, 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.
