I considered going as an OC for one of my friends who has been writing a book for the past year or two, but decided not to since I would get mistaken for a Near, Death Note, cosplayer if I were to dress as him. Even though they dress differently he is a strictly white clothes dresser as well. Anyway, I personally commend you for going for it and cosplaying one of your own characters! The more originality in this world the better I say.~
P.S- I'm pretty sure you posted this thread in the wrong section. This would belong under "Cosplay" not under "Plan Your Own Adventure".
