i love love love these tops, i bought one in black and one in the ivory color.
i disagree with the others that they make you look flat chested. i do not experience that even remotely nor do i know how others could experience it unless you're "really" small busted.  its sort of a modest cut, so it hides cleve, so maybe that's what they're talking about.
i've recently lost ~90pounds but i'm still sorta' biggish at a size 14.  i needed something to smooth out the belly lumps while i continue to lose weight but wanted to wear clothing that is tighter fitting.  these tops totally do the trick.  they don't take off inches but they smooth you into more of an hour glass rather than a lumpy belly.  they're good for the muffin top too, as long as you wear on the outside of your pants, which is great for the little lacy details.  and after about three weeks, neither of them has ever rolled on me.
also, good for working out because of the compression.
they're easy to get on, but a little bit difficult to get off if you have broad shoulders like me.  i have to take them off by tucking one arm down into it then lifting over my head.  but that's not bad enough for me to deduct any stars
