They are REALLY sexy. Some girls don't know how to wear them, and it can look ugly, but if the girls wears them good, it's a turn on for me. If a girl has them and we're about to have sex, I won't take them off.
I'm more Of an over the knee (which is whys in your pics), than knee high. I think they're cute yet sexy. Also hen layered over tights I think they're so comfy and warm. I they're awesome, you should define key try them
