Athleta One Piece Swimsuit w/ Back Cutout Sz M

Awesome like-new swimsuit by Athleta. VERY gently used condition- worn 3-4 times. Nice thick fabric with cutout at back and wide shoulder straps. very modern, minimalist suit. Fits a bit snug for a medium on my body, which I'd why I'm listing it. Would probably fit a size 6 very well. ***Willing to swap for a large.
