Jantzen Retro-Style Polka Dot Swimsuit size

Fully lined and in good pre-owned condition. No stains or holes, there is a small run in right buttock lining and a hand sewn-in ruffle was removed by me from the top inner front lining. See photos for detail. It's about 16 inches pit to pit and 23 inches long from the point where the bra cups meet.
