Build Your Wardrobe with the Crosby Swimsuit
The Crosby swimsuit is the ultimate feel-good swimsuit, with a surplice bodice, shirring at the side seams, a supportive shelf bra with optional foam cups, cute convertible straps at the back, and just the right amount of coverage, without sacrificing style.
Sew it up in swimwear fabrics that have 4-way stretch, and don’t forget the swimwear elastic.
