I am impressed. First fat smoosher-inner thingy that has ever truly worked for me. My only complain is around the tops of the thighs- you can def see where this thing is. It isn't smooth if you are looking to not have panty lines because it certainly shows those. As far as belly goes, though, it does smooth the crap outta that. I like it. I am a size 8 with average size hips, and bought a medium.
