Oh you also live near DC? Well maybe I'll see you at the convention! ^_^ I'm actually cross-dressing as Saber Lily from Fate/Unlimited Codes. I won't pull off the feminine streak tho, so I should be easy enough to spot...
If that's not enough, I'll be carrying around 2 Black Polypropelene (or whatever teh fuck it's called) bokken and performing with them (mainly just using my modest martial arts experience)
