Well, it depends. I'm going to give myself a bit of time to start a regimen. I want to do Akihiko from Persona 3/P4 Arena. I figure I'll make the Evoker and get the wig, and after a certain amount of time, decide if it's still feasible to get in shape for P4 design(shirtless and kind of buff), or if I should just go with the thin P3 version.
No matter the con, no matter the experience. We are cosplayers. And we are one.
