I put this on (I had to step into it and shimmy it up my body) and then HOLY FIRE!  It totally sucked in my love handles.  It took 2 inches off my waist and didn't constrict my chest at all. I put it on and went shopping all day and it was great.  It was a bit constricting when sitting for long periods of time, but otherwise totally comfortable.  I am 5ft 145lbs and I got the medium.  It totally helped the baby belly left over from my last pregnancy.  I want one to wear every day.
