My family is heavily involved in the Marines and close-combat training, and I was raised doing Japanese sword training, so I've always been of the mentality that you have to be able to defend yourself.
I think that men's clothing should be functional. If there's a rip in his jeans, it should be because he was out working, not because he ripped them so they looked cool. It's even better if they're ripped because he got in a fight.
