Sorry, but I'm with Matt on the Kefka thing. If you really want to dress up like Kefka, I honestly don't remember what he was wearing...

Also, I've never cosplayed before, but I've been to an anime convention, and a halloween party, and the spirit is much the same. It's fun to wander about and see what people have come up with. Oh yeah, and I was dressed up at the halloween party. I don't think there is anything inherently wrong with cosplaying. If there is, then there is also something inherently wrong with dedicating 40+ hours of your life to a final fantasy video game. And that, I am not willing to accept.
