These leg warmers only come in one size, and it doesn't fit all. I am 5'4" 125 lbs and the cuffs are very tight around my legs. If I wear them just above my knee (where my leg is 15.5" around) it is very restrictive. If I wear them just below my knee (where my leg is 13" around) it is still restrictive. If your legs are super skinny, you'd probably be okay.

I ordered these leg warmers as part of a Halloween costume, so it's not a big deal. I will try to stretch the cuffs out a bit. If I had intended to wear them daily, I would probably return them.

Aside from size, these leg warmers are nice. They're bright, they have a nice thread-count (so they're soft), and seem to be well-made.
