At kcon 08 I dressed as a darker version of Ritsuka from Loveless, I just wore a bunch of black, mesh, and a collar I had. We came up with it being Ritsuka all dark when he's older or something, just random and fun and it turned out to only looosely be based on Ritsuka in the end (yet it still seemed the crowd favorite out of all my costumes, haha). What was hilarious is I got called "emo neko" a lot.
So, I've decided that next year I'm gonna wear the same outfit without Ritsuka's hair, ears, and tail. Instead I'll make brown cat ears and tail to match my hair and VOILA, I'm gonna be a catboy. It's always so fun and I feel cute while doing it (which is rare, hehe). And the looks on people's faces make me laugh when they find out I'm a catBOY. =P
Can't wait! <3
