Not sure where to start...first of all, it doesn't slim you so you can wear tighter-fitting clothes (and I'm not talking a miraculous 4 sizes or anything, just clothes that have become a smidge too small...or normal clothes at that time of the month).  Contrary to the picture, the fabric is so darn thick that it just adds bulk, which renders it pretty much pointless.  Also, the fibers are not smooth, so dresses/pants catch on it, and you constantly have to adjust and tug to get your clothes to lay properly.  The waist is too loose, the top rolls down, and even though there are technically no leg "bands," the bottoms dig in, so it's blatantly obvious that you're wearing them, especially under pants.

What a colossal waste of money.
