been to a few cons myself, mostly dressed as an anime character. one i went as SPike from Cowboy Bebop (I have the right body type for it). Wolfwood from Trigun a couple times, and once, just once, I played Commander Amarao from FLCL, and my girl friend at the time played Kitsurabami.

I always wanted to play as Lupin, but I'd have to go first series lupin, caus I don't wanna where the white pants, even though the red jacket is very cool.
