No. Real men don't wear tights except for cycling or under running shorts in cold weather for exercise.
So don't try starting a trend but if you must, keep it up in Canada, we have enough girly men down here as it is.
Seriously, I love the feel of them on a cold day but no, we are just short of walking around in public in our underwear as it is. There is little decorum, class or common sense left when going out in public any more. So no, emphatically NO. Frankly, I don't like seeing the women in skin-tights out in public.
