1950s swimsuit with back zipper and adjustable straps Size M

This suit has an amazing print! It's made of what feels like a polished cotton with some stretch. There are three button holes on the back of the straps to adjust for fit and elastic across the back. There is also a center metal zipper with inside hooks. It is lined with cotton. There is boning in the bust. It still has it's stretch, even in the legs. Unfortunately the tag was cut out so I don't know the maker. Flaw - if you look carefully, there are some brown age spots on the front. They blend in with the colors of the print so I didn't see them at first. Otherwise, in good to very good condition. Measurements Bust 36" - 38" Waist 28" Hips 40" Length 31" shoulder to crotch with button at it's shortest
