These are really warm and look great. I wear them under my pants for work (it's cold there!). But they're supposedly one-size-fits-all up to size 12 or 5'6". I'm size 10 and 5'3", and these tend to slide down a bit for me. They're just not quite long enough. That said, it's not enough of a problem to stop me from wearing them. They're still a great pair of tights.
