I am 5'4, 130lbs, In jr sizing I usually take a M or a L.  So I ordered a Medium.  These were gigantic.  Waaaay too big and Waaay too long. I couldn't even keep them up.  I don't think even a small would have worked.  I was shocked because many reviewers said they were too small.  So the sizing on these is waaaay off. The waist is also awkward and would fit in an unflattering way. The crotch area is small and they are definitely meant to be low low waist. Just not a good buy.  I returned immediately.
