Our Madewell Second Wave swim collection has a built-in feel-good factor—the fabric was made using recycled plastic (aka, this piece = three water bottles). And the look-good factor is no joke either. Crafted from embroidered eyelet material, this feminine ruffled bikini bottom offers just-right back coverage. Nylon/elastane. 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. L4842
