I'd suggest sizing DOWN one or maybe two sizes. The cut of this corset is odd-- it's very very curvy. The waist is much smaller than the top and bottom. You need to tighten it quite a bit to keep the top and bottom from gaping, like it is on both models. That said, this thing is cool and could be part of lots of fun looks. Just don't get it too big, because there's no way to take it in once the lacing is closed.
