Hi, I'm really hoping to go to Otakon this year. If I do go I think I will only be bringing with me two costumes:
Yami Bakura from Yu-Gi-Oh! http://www.cosplay.com/photo/1459396/ The Yugi cosplayer in this picture with me will also be there.
Abarekiller from Bakuryuu Sentai Abaranger http://www.cosplay.com/photo/1424324/ Not anime but Japanese related. Wore the suit to Sakura Con and people loved it, lol.
