It's a good idea for when u want to wear shorts and it's a bit chilly of if your school dress code prohibits short shorts. It doesn't look that bad if done well, but I'd rather wear shorts with over-the-knee socks of nothing at all.
i never wore them together but there is a certain way 2 wear them they have 2 b booty shorts with either striped of neon tights (at least in my style) :)
Okay, this depends on the look you're trying to get, the colour of the tights and what you're wearing with it. For me though, Totally cool xx :) Hope I helped
