Let's see......
I'm doing a cosplay of Hughes from FMA (button up shirt, doing hair, makeup and glasses!)
Friend 1 is going as Sora and will be spiking his hair and wearing normal clothes (wondering if he should bring his keyblade? I said no, but what do you think?)
Friend 2 might be wearing a Shinigami outfit from Bleach.
And friend 3 isn't sure, and might just dress in crazy clothing.
