Rare Vintage 90s Peep Open-Back Bodycon Dress M

I would wear this dress out dancing in my 20s when I wanted to feel hot and stand out a bit! classy but brassy! think Julia Roberts in Pretty Woman* this was not in the early 90s, it was vintage back when I wore it, too :) there's no size on the tag but its too big for me now and there's some stretch to it... I'm an XS, so my best guess is this is a Medium. it rests on the shoulders but with an open back, you gotta have some real estate to make it work, wide shoulders or big titties. I used to have the latter so made it work. not super mini, but just above the knee on me and I'm 5'4. this could be 80s not 90s, the tag looks a bit more 80s but the vibe to me is early 90s it's in good vintage condition, the black could be a tiny bit darker but it's not faded, the fabric is smooth and not pilled, God I love this dress. I hope it finds a good home.
