Its pretty sad to get so excited about under garments, but these are exactly what I needed and are a total lifesaver! I ordered these specifically for chaffing as Im pregnant and have gained weight so my thighs are rubbing together which is driving me mad especially in the summer heat. I wanted something not too tight since Im obviously not looking for tummy control, but something tight enough to stay up and these fit the bill perfectly! The material is not too thick and not too thin and they don't role down when I sit. The length is also perfect and doesnt show beneath my dresses. I imagine if I wasn't pregnant these probably do offer a bit of tummy control, but they aren't nearly as tight as something like Spanx which makes them way for comfortable. For the price, the fit and quality I couldn't be happier!
