I personally go for natural colors or tans, but I sometimes like to wear a tight, shorter skirt and and wear black nylons. With four inch heels of course.
I agree at first I was only into black pantyhose and stockings, as soon as I started wearing the tan and natural colors I was hooked and definitely prefer the natural shades that give my legs a more natural realistic look. I just feel much more sexier in those shades, of with my black leather mini the black stockings are a must.
