While I think in time this really would have worked, I'll never know because a few of the clasps are coming out already. It's very unfortunate since I feel like after a couple weeks I was already seeing a little bit of improvement. I'm 5'7, 130 lb, and I have a 29 inch waist. The first time around I ordered a small which was way too small. I then ordered a medium which worked. I was wearing that on the second set of clasps when they started to pull apart. Part of me wants to return it for a new one in hopes that it was just a fluke, but I may just try another brand.
