This is a very nice outfit. The lace is pretty and black will get pretty much any guy going. I don't know why that is...Anyway, it doesn't cover much of the butt, but I think that's probably the point. It says one size, and it has a lot of stretch to it, so I think it would probably fit a lot of different people. I'm a size 10 normally, and it fits me just fine. I also like that the halter is a fixed halter so you don't have to mess around with tying it or anything. So if you want to surprise your man with something sexy, this would be a good call.
