I bought this dress despite the bad reviews. Yes, it is pretty thin fabric. The silver triangle and fins are just foam. It's really short. BUT - I am short. I'm 5'1''. If you're a giant, where leggings. Or fishnets like the model. I did and it completely worked. I was curious about what the back looked like, it's plain black satiny fabric. I am busty and I was kinda worried about the strapless business, but it actually holds up nicely for being so thin. Flattering even on me. You should buy it, for $40 is very good.
