I have been looking for thick(ish) supplex leggings for a while. They hold their shape and colour better than cotton spandex (and less linty). These ones were spot on! I'm 5'3, normally wear a 0-2, and went with a S after reading the reviews. The length is perfect and sits just at my ankle bone (which might be short for tall people), there's still a little room to stretch, perfect, as i didn't want it too tight.
