These are great! I'm a US women's size14. I ordered the nude unisex size c. They roll just a tad, but for the most part they stay in place! I wore a dress/skirt with these bands for 4 days in a row! With NO chafing!!! I don't have to wear shorts when wearing dresses/skirts anymore!!! I am so excited about this!!! I just went to the Kentucky Oaks and wore the bands under my dress! It was a hot day, and they stayed in place all day! No soreness of any kind!!! I can't express how happy I am!
