Patagonia Reversible Bikini Set Soft and comfortable swimsuit, made for water sports. With ruching at the bust, this halter-style bikini top crosses in back between the shoulders to keep pressure off your neck Top has straps that lie smooth and flat for easily layering under a rash guard or wetsuit top. Bottom has a straight and low fit across the hips, with narrow straps that wrap around the front and a minimal-coverage seat for reduced drag. Made from recycled nylon and spandex jersey Fair Trade Certified™ sewing I THINK this is a large, but there are no tags to confirm. The top was way too small for me (fit like a medium) so please refer to photos for measurements. *See photos for measurements* I have never worn this because it didn't fit me properly so it is in like new condition.
