Ahh so glad there's going to be a Teen Titans group! I'm bringing my Terra. Not sure which day I'm wearing it yet though, most likely Friday or part of Saturday.
Saturday - Romano Vargas (Hetalia)
Sunday - Gakuen Arthur Kirkland (Hetalia)
Costumes in the works
Tinkerbell (Peter Pan)- Halloween 2011
Undertaker (Kuroshitsuji) - Chibipa '11/Megacon '12
