Exactly what I needed for my costume and looks/fits like an expensive corset.

I originally ordered a medium, based on comments/size charts. Even laced tightly it was a bit big and the shoulder straps were too long.  I returned for the small, which fit fine and didn't needed to be tightly laced.  Shoulder strap length was perfect.  FYI, the small fits a 33" bust, 26" waist, and the top looks better when the lacing is spaced apart rather than tight.
