Love the Spanx line. I've been using this line for years. Works wonders to make panty lines disappear and gives your slacks a smooth look throughout. Highly recommend this item and the rest of the products in the Spanx line.
Like other reviewers have said, they roll at the waist which is super annoying. Also, the "control" part stops mid thigh and I was wanting a smoothing effect all the way down. All in all, I am glad I got them on sale because I was disappointed.
