First impression was there is a "panty hose" feel to this. My maiden form slip shorts are a lot smoother type of material. Not at all like panty hose, but they do not stay in place as well as these.It is thin, definitely not for shaping but excellent for smoothing and wearing under dresses/shirts for chafing.Pro-They don't roll down from the waist. The legs stay in place except for when sitting down-they move up but in no means bunch. Still provides excellent coverage after sitting. I do not feel the need to pull them down. Initially they are about three inches above my knee then move up a few more inches after sitting.Con- they seem to stick slightly to my cotton and stretchier skirts.**the seams on the thighs are apparent through tighter skirts.They are definitely not as smooth as a slip.But it is not noticeable. Still works fine.Overall great for chafing and just feeling covered up under a skirt. I wear these with underwear and not alone.I am 5'5 and weigh 165. I bought a large and it fits perfectly. I have longer legs and a shorter torso. (If that helps any)***Update-Unsure how, but they now have a small runner and are starting to ride up a lot more. I don't think the price is worth it as I just found a similar pair at Walmart for $8.... they are a lot more slick than these and are true slip shorts.
