I'm 5'2" and 120lbs. I typically like my leggings not so skin tight. (They are really tight, but I do have thicker legs) I do a lot of squats, etc when exercising and do not like it when my leggings become see through. I ordered the xs. They fit fine for just everyday wear. However, they are a little too tight for other activities because they become see through when doing squats.
