its not one size fits all at all. im 5'8, like 145 pounds, and i wear a M on bottoms and i couldnt even get these past my thighs even after i stretched them. youre better off just going to the beauty supply and getting some pantyhose that actually fit for less

I ordered these to wear with my costume but they are so short! The size was fine but the length is very short, they couldn't got past my thighs and I'm only 5'4 150 lbs. I also was not allowed to return or exhange, so it was a waste of money.
