I used to wear bicycle/compression shorts under dresses to help with chaffing but those aren't always practical, they can easily be seen either through the dress or sticking out the bottom and sometimes it's too hot. These are great! I honestly can't say enough good things. If you measure correctly they will fit. I had no rolling issues and they look really cute. I measured and wore them as high as I could on my thigh at the very top, that's my thickest part. I did angle them a little down in the back due to the butt/thigh crease was rolling them. The silicone did start to feel a little uncomfortable but I had been wearing them for a good 6 hrs and it was hot and sticky out.
