How many other One Piece cosplayers should I plan on seeing? I'm going to be Zoro and my group consists of a Nami, Usopp, Luffy, Vivi, Sanji, Chopper, Robin, and Carue. We will be out and about in these costumes on the third day. Any one else coming in a One Piece costume? It'd be great to get some pictures of other characters, perhaps some of the villains.
