This is a REALLY COMFORTABLE shaper.  Contrary to the negative review, I have actually worn this several times and find the material  to be light-weight, invisible under my dresses, and it stays comfortable even in CA summer temps of 95-105*F!  It probably won't cover up major tummy rolls, but provides light slimming and smoothing, and the high waist helps smooth torso lines (love that!).  I'm size 10, but based on reviews, I purchased a large (nude), which fits well.  I bought a second one in black, size medium -- I like that fit even better.
