This thing is amazing!!  It brings my waist down at least one size and smooths out my tummy. It is kind of difficult to get on but once you get the hang of it, you will be fine. My biggest advice is go with your true size. Dont size down for extra results. I am a medium normally but thought Id get a small so I could get an even smaller waist. I got it and it was way too tight. I could barely get it on and when I did, it wasn't comfortable at all. Exchanged it for my actual size and I am so happy. Highly recommended!
