K.C.
Hi,
I do have one. I bought it 1 size smaller. When I wear it on a regular basis it drastically improves my posture which visually takes a few pounds off becuase you are standing straight. However, I did lose some inches. I noticed when I would try on clothes. Because it is sooooo tight I was forced to eat smaller meals or I would suffer much discomfort from being too full which aided in some weight lose. However, because of the hassle of putting it on and taking it off I stopped wearing it like the directions state BUT I wear it occasionally and I DO get many complements about the weight I have lost...LOL.
Hope this helps!
