I bought two colours of this sock... though I suppose "shade" is a more appropriate term. Anyway. light gray and dark gray. These socks are meant to run way loose and WAY long, but I have both really long and fairly wide legs, so I figured this would be a good way to go for me.
I wear these about mid-thigh, cuffed.They stay up really well and look great layered over leggings, tights, fishnets, or nothing at all. Since the over-the-knee socks send to send a strong (and somewhat... er... sensual) message, I keep the rest of my outfit fairly conservative. I think this look can be applied to just about any occasion... comfortable enough to lounge in and chic enough to wear to any party.
