Personally, I think you can wear whatever you want to cosplay, as long as someone can look at you and guess who your character is. BUT it wouldn't be considered "kosher" and you might not get as much recognition for it, unless it's really cool-looking. (And you wouldn't be allowed to include the pictures in ACP as a cosplay.)
Just my 2 cents....
okay good to know. what would it be considered as, then? fanplay? lol XD I'm sad I wouldn't be able to post the cosplay here, though, and I guess that also means I couldn't really enter any contests either. I showed the drawings to a few people without saying anything and they were able to tell who it was right away, so I suppose that's all that matters!
