As you can see on Flickr::Elmascaras, tights can be worn as part of a regular outfit. You don’t have to look like “I just went to the gym” or “I’m a sneaky perv” but rather, the way he wears it, you see a confidence in his style, no excuses required. Very well done.
Some notable examples:
Gray tights and a jacket
A darker look for the subway
T-shirt and tights
This reminds me of when tights made a bold showing on the Milan runway in the Spring of 2007.

On the other hand, wearing tights with a skirt and a tie must be a fucking joke. Or some dumbass is trying to abort this fashion baby.
More commentary.
