STYLETHREAD -- LET'S TALK SHOP!

We are going to a masquarede ball for halloween and I need to find a costume. I want a ball gown that's more like a halloween costume, very over the top and sexy, but not a ho costume, you know? It seems like all I can find is trampy "fill in the blank" costumes. I don't want to look like a prostitute at this thing, but still want to be sexy. I want something with a big skirt that's short in the front and long in the back. The only thing I've found that I like so far is this:


But I am concerned about the boob part because it looks like a cheap shiny material and I have big boobs so the last thing I want to do is make them shiny like "HI HERE ARE MY BOOBS!!" I really like the rest of the dress though. Anything similar out there?
