I'll be cosplaying Isshin Kurosaki from Bleach, as he is the only character that I actually look like IRL and can really pull off well. Gigai form while I'm standing in lines, shopping, etc. Shinigami form for everything else.
My girlfriend decided to go a different route this year and settled on Kagome from Inuyasha.
Her brother will be cosplaying Yahiko MyĆjin from Rurouni Kenshin. He can REALLY pull that one off extremely well!
