Love these sweats, fit is great. I am 5'9" with an athletic build and pretty thick thighs, 31 waist, so went with a Medium but the fit is awesome. Tapered without feeling too tight.
Probably will pick up the black pair.
FYI, grey sweats come with a grey drawstring and not white. It's a small detail but I was really into it from the photos. Still happy with the pick up though.
