There wasn't a specific size so I just ordered it. The shipping was good but when I tried them on they were much too tight. I'm 5'5 and I weigh 120 pounds which is pretty average. I do have thick thighs but it wouldn't even go beyond my knee. I gave it to my friend who is much thinner than me. I recommend this only for thin people. However the seller for this product is very kind and offered to fully refund my purchase which is very rare these days. This is great customer service which I appreciate more than the product.
