I bought a medium and the fit is as expected, however being totally seamless means everything is a cut edge, and being a super soft, stretch fabric, that means every cut edge ROLLS. Like completely, all the way down. Maybe under tight jeans they wouldnt roll as badly. However I was wearing them under scrubs to avoid panty lines, and they just aren't going to work - very annoying to feel your underwear all rolled down in a bunch! I don't really like the thought of returning underwear, so Ill take the loss on this purchase.
