A thought I was just having while reading this was, how would you make a character in a school uniform recognizable when doing them as the opposite gender? That seems like a huge challenge, especially if the character doesn't have one of those unique hair colors. Of course people would be able to tell the show you're from based on the cut/color of the uniform, but other than that it seems like an impossible task.
