I love these! They are a lifesaver under my more form-fitting maternity dresses that are made of cotton and stretchy modal material.  No chafing from stubble on your inner thighs with these!  The only thing I don't like is that they are the stretchy nylon material that makes you sweat, and of course that material also holds odor unlike cotton underwear and traditional, loose, silky slips.  Ive found that during pregnancy, however, beggars cant be choosers and that you're lucky when you actually find something that works at least partially decent!
