J. Crew V-Neck Plunge One Piece Swimsuit Our best-selling V-neck swimsuit is always ready to take the plunge. - We think this one's pretty stripe-tastic... Polyamide/elastane. Lined. 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. Worn once. I’ve lost weight and sadly this no longer fits. Size: 12
