I was going for denim leggings, but these are more like jeans.  I like them.  They're a nice thick material, but stretchy.  However, unlike many other pairs of stretch denim that I've owned, they don't seem to shimmy off my body as I move throughout the day - BONUS.  They even have real back pockets!
I'm 5'6" and 165 lbs.  I ordered the 12 short and they fit more like a cropped pant, which is fine since we're going into spring/summer.  I could have gotten the regular and they would have fit fine - it's hard to tell, because sometimes "regular" are still made to 6'+ supermodel-tall Amazon women.

Anyway, I like these, especially for the price.
