I relay like this corset. I went by the measurements from the company, then took the advice of other reviewers and went a size up. I got a large in the black and red corset. I'm 5'4" at 125 pounds with a 29 inch waist. The laces on the back are cinched all the way except around my hips there is a half inch gap in the back. I could have gotten a medium, but it fits well enough. The material is very nice. It's firm as a corset should be and the quality seems to be pretty good. I'm satisfied with my purchase and would recommend this for other women.
