I ordered the gold metallic leggings in medium, item came as described, as well as fast shipping. The material is very thick, is not meant to stretch. I think if it were to stretch the material would rub off or maybe break? The waist line is stretchy, so I feel like it would fit all sized mediums. But may be too long for shorter legs. I have not yet wore these out; but when I do, I will update more.

My sizes:
5'7"
32"26"38"
Pants between 4 and 6
