I bought the grey flannel colored tights in a medium, and I'm 5' 4", 120 lbs. It is a good fit with a tight weave for more control overall. It's difficult to find tights in the dark grey, but I do prefer a more blue/grey than the brown/grey of these tights (the reason for a 4 rating). The tights are pricey, but Nordstrom's was the only store where I found dark grey.
