I have large thighs and rarely wear dresses or skirts without leggings or spanx because my thighs rub.  I got so excited when i found these on Amazon.  Unfortunately after wearing them around the house for one day, they started to roll down my legs and i had to keep pulling them up in place.  By the end of the day they were stretched all out of shape and it just wasn't worth the aggravation of constantly having to pull them up, so no bueno for me.  Great concept but didn't work for me.  Perhaps it works better for others.
