I bought this footless tights for myself and it is size medium. I was surprised to received it because it was short and very small. The seller listed the weight and the height for a person that can wear it. It was big for me base on the measurement provided. Anyway, I was skeptical but when I tried it on, it was stretchable and now I am comfortable wearing it. I like the idea that it is footless. Bought this for under $10.00- that is what I love about shopping on eBay.
