I bought these post fat grafting surgery. I need to have compression on my thighs for three weeks. I and 5' 6" 117 pounds, normally wear an XS in things and bought a small. These fit well. They are soft and comfortable. These only go to my mid-thigh, about 4 inches above my knee, which would be a good length for under dresses and skirts. For my use, I could have used something longer. I have been wearing for about a week and they are holding up well.
