I've always been a little skeptical of the one-size-fits-all thing. I decided to give these a try because of the ratings. Ordered 3 pairfor my daughter last Christmas. She absolutely loved them! When I wanted to order some for myself, I decided to order 3 pairs for me. They are the best fitting, softest, most comfortable leggins I have ever owned! Mind u, my daughter is 5'5, 125 lbs and I am 5' 0 112 lbs. These leggings fit both of us perfectly. Super fast shipping as well. Great product, HighlySee full review
