I think if you wear that sort of stuff with confidence, you can get away with it. If you look self-conscious about what you're wearing people are going to think they aren't for you.
I looooove my royal blue tights... so glad winter's coming up so I can wear them again!
All I can say is unless you have thin legs please don't wear these metallic stockings in public - Fashion is more flattering when it suits your body type. For some girls who don't have the legs stick to something that makes your legs look sexy.
