It fits just as expected. I had surgery on stomach when i started using it a month ago it barily fit. Now it neeeds to be smaller and it does go smaller and can even go even smaller. This is the only one you will need i started with the 3 belts and down to using 2 belts its nice to have 3 so you can choose which ones to use. I wear under a tee shirt not bulky. I'm 4ft 11 1/2 in 117 lbs if this helps anyone. I will probably buy another one in about 3 minths only because i wear everyday.
