I was very skeptical of these, but tried on a whim since I really want to wear dresses comfortably this summer. I typically wear spandex shorts that roll up. I measured my thighs and ordered the exact size they were. When I wore them, I wore them as high as possible and at an angle so my inner thighs were protected and they weren't too long in the back. This caused a slight roll under my butt cheeks, but that was my choice to wear them like that. These things are AMAZING. I wore them them for almost 14 hours and they never moved or rolled, even when I was sweaty. At first when I would walk, I felt conscious of them because they felt like they were falling down so I did a few checks but they didn't budge an inch,its just the way they feel. I will be ordering more and now have the confidence to wear a dress every day!
