Everything is more flattering with a bit of ruching. - Case in point: our new one-shoulder take on our best-selling one-piece suit, in a sweet floral print. Plus, this style was crafted with nylon made from recycled materials that could otherwise go to landfills. 82% polyamide/18% elastane. 92% polyester/8% elastane Repreve® lining. Removable pads. Our swimsuits are machine washable, but we recommend hand washing, as it helps keep the fabric and shape of the suit looking newer, longer. Import.
