I'm definitely doing a Gackt Mizerable (coat and all) at Otakon, which I'm spending a LOT of time perfecting, so it should be one of my nicer costumes.
I've only crossplayed once before (Harry Potter in the cosplay at NekoCon this last year) but it went over so well that I've been prompted to do more guys. ^_^* I'm always so stuck on the frilly girly costumes...but I'd like to give more guy-cosplay a shot!
After Gackt, I'd like to do a few more guys but I'm not sure what. I think maybe Klaha (since people say my face is something like his), and maybe Dewey from Nurse Angel.
