NWT J. Crew Ribbed high-rise cheeky bikini bottom in black We re-imagined every single suit in our swim collection using... over 60 percent recycled materials to help keep waste out of oceans and landfills. These high-waisted bottoms are crafted from a special fabric that incorporates recycled nylon. Our '80s-inspired cut sits higher on the hips and waist for a streamlined fit—and now has a little less coverage in the back. Plus, we added some ribbing to the fabric for the perfect touch of texture. 81% recycled nylon/19% elastane. 92% recycled poly/8% elastane lining. Our swimsuits are machine washable, but we recommend hand washing, as it helps keep the fabric and shape of the suit looking newer, longer.
