I’m boarder line medium small so I wish I knew how stretchy the corset’s material was. I probably could have gotten away with fitting in a medium. But overall I love the top it’s exactly how it looks in the photo and gives the illusion of a snatched waste. The only con about the top is the wire at the top of the corset were poking my skin but I was able to fix the problem but pulling the extra fabric to layer over the wire.
