i think i posted just a one-piece bathing suit
rather than 50s style suit
a 50s style..
it's one with the halter neck, no?
and with "short shorts"
i agree it's kind of sexier because it sort of accentuates the curves
like what you call those..girdles..

that are elastic and are supposed to firm up the body
rather than a bikini which just cuts the body up
