The t-shirts I wear are mostly music, game, or superhero related, but I also wear solid color and striped polo shirts and the occasional Hawaiin shirts (I'm big, so I'll always be able to find one in my size). My pants are most often blue or black denim jeans, sometimes khaki cargo shorts, or khaki Dickies. My hair is either short or medium length and my facial hair is normally a trimmed beard or goatee (it's all shaved off now and it makes me feel naked). And my shoes are New Balances (for added arch support).
The stereotype I like to go with is comfortable. =D
