I wear my camo pants and uaualy a military-esque shirt everywhere I go. So I don't find much need to differ for airsoft games.
I obviously don't look like I'm 'on duty' because it's not a complete uniform and my hair's pretty freaking long.
But I also don't look terribly threatening either.
I mean what would they think I was gonna do? 135lbs of prettyboy comming at you with a plastic knife? Lots of terror there. *Punt*
Then again, a couple truckloads of guys wearing camo pants is a little different.
I still don't think it's that big a deal.
