-- FIT ----------------
These definitely run on the small side (per the size chart and other customer reviews). I'm 130lb, 5'5'-5'6' with long legs, normally a 2-4 in women's pants, so I tried the Large.  They fit, but not great. They cut off a little short on my ankles, and sit a bit low on my butt. My butt's pretty small and these barely cover it, if you're on the more well-endowed side of the booty spectrum these definitely will not fit. If I squat down they slide down my butt and would flash whatever I'm wearing underneath. So they'd be fine if you had a long top to cover (like wearing under a tunic type shirt or under a dress), but if you wanted to wear these as pants with a crop top, they wouldn't be great.

-- QUALITY ---------------------
They smell a bit plastic-y, but the matte finish looks nice. None of the seams look shoddily stitched or anything like that. There's not a lot of stretch to the fabric (it feels a little plastic-y as well). Overall the quality is totally acceptable for the price.

-- VERDICT --------------------
Not bad for $12 leggings, especially if you're just looking for something to use as a layering piece, but I've honestly gotten ones that fit better and I enjoy more from Forever21.
