I like it when people swap genders for dress. I don't really know why, but it draws me in. Even when it's not really merely androgynous. When Scott Westerfeld gave his talk at LeakyCon this year someone asked him why Deryn dressed as a boy and he said that it was simply because he'd always wanted to write a character who did that. I can relate. In the original outlines of the Steampunk Amelia sometimes dresses as a boy. In my head she still does, but I don't think that it'll end up on the page, given the time period we're working with. Maybe for book two.
Is there a time when your character has been found out for being someone everyone else thought they weren't?
