One Size Fits 0-10. Black Thick Winter Fabric Leggings. 85% Polyester & 15% Spandex. L: 34'' W: 10'' IS: 24'' *please note, there is 15% spandex! Alot of stretch - when you first get these the waist looks small but they fit right on (believe me, I am a size 10 and weigh 145 and these stretch to a waist of 37 inches with no problem at all - not tight and not cutting into my belly!) they are my favorite thick winter leggings! You will love them 💙
