I suppose if you were in a situation where you wished to conceal or obscure your presence, wearing camouflage - pants, shirt, smock, jacket, hat, whatever - might make sense.
You know, like if you were a wildlife photographer stalking dangerous or easily spooked game in the wild. Or if you were engaged in some sort of military exercise where you didn't want your position to be easily determined. Or situation like that.
But I confess I have no particular expertise when it comes to the donning of camo gear. I'm just speaking from a common sense perspective.
I suppose it's possible that it's currently the height of teen fashion to wear camo gear to school or for a trip to the mall. As you're 16, and indicate that you're aware of men's styles, I'll have to defer to your opinion in this matter. Sure, wearing camo gear in such situations strikes me as silly, but no sillier than, say, paying a price premium for pre-ripped jeans, or sagging, or any number of other fashion-related behaviors which I know are/have been popular with some people.
