I bought a larger size than I usually wear, thinking it would fit more comfortably. When I opened the package I couldn't believe how small it looked. I decided to try it on anyway. I put one leg into it and there was barely any room for my other leg- and this thing was supposed to fit over my hips and bust? It did actually stretch to go on, but it was awful. I didn't even see a difference in how my dress looked on me with it versus without it. Certainly not worth the discomfort or cost.Fit true to size. The slip hit just above mid thigh, is low cut enough in the front to not be seen with my clothing. Like the other reviewer, I don't HAVE to wear a bra, which is nice. The nude color is not noticalbe under the cream colored dress I wore it with. I have hit-or-miss luck with shaping garments, and am happy to say this one is a keeper, price is an added bonus. I will have to check out this brand more in the future.It has firm support. Totally recommend!
