I wear my "NPC" shirt to work, occasionally when I'm grocery shopping. Of course I live in a small farm town, so I have yet to have it recognized, or even have anyone ask about it. My other two "gaming" shirts I don't wear, one is the much talked about "crap" shirt, though my is the more explicit version. Then I also bought an elf porn t-shirt, is says "Got Elf" with a near nude anime elf on it. Again, conservative small farm town, folks probably wouldn't appreciate either of those shirts.
