I probably should have ordered the next size up.  Even though I ordered the size I wear, I had a lot of trouble getting this on.  However, I will qualify that with the fact that I have a back and shoulder injury from a car accident where someone hit me when I was at a dead stop, so I am not sure whether someone who isn't compromised would have been able to get into it more easily.  I did finally get it on, even with my handicap, so that says something.  I am used to a medical corset, so I wore it for longer than they recommended for the first day (they recommend starting with 1 hour the first day, 2 hours the second day, etc).  I wore it for 4-5 hours the first day, since I wear the medical corset that long.  It did slim my figure while I wore it.  I don't know whether it burned away any fat, but it was only one day.  I think I am going to wait until I lose a little more weight before I try it again just because of my shoulder and back issues.  It hurt my shoulder too much to struggle into it.  Maybe I will have my husband help next time.
