This photo appears to have been taken in the late 50s (the note on the last post of it claims that this lady was a carnival worker -- the hoochie-coochie illustration in the background making the point), but the general presentation of the subject looks rather anachronistic because of the co-opting of the fashion establishment of vintage lingerie and dress styles in recent times.
She's very sexy, in a way that feels post-modern, and she is showing a lot more cleavage than was generally thought proper in the apparent times in which this photo was snapped. She is a tawdy lady, a carnie, a real hot number. I would love to be able to see a film of her act.
Many Thanks to Atompunk
