1980's does 1950's ONE PIECE SWIMSUIT pin up S

Looks like a 1940's/50's style, but it's actually from the 1980's! Crinkle pink outer layer, and full lining inside. The front tummy is lined with power mesh for great hold. Shelf bra with lightly padded soft cups. The bottom elastic on the shelf bra has gone a little weak from age, but doesn't show on the outside. Tagged as a US 10, but definitely runs smaller by today's standards... I am a 6, and I had no extra room at all. Definitely for a S. When laid flat, before stretch, here are the flat-across measurements: 16" across the bust, 12.5" across the waist, 16" across the bottom (hip/bum). 28" from the shoulder to crotch. Nothing wrong with that back strap in the modeled pic, I just didn't realize it was twisted when I took the picture! (N10)
