[ sookie can relate to the stereotype nonsense getting annoying, being what she was. her outfit in particular was her way of mocking what everyone expected her to look like once they found out she was a faerie. making fun of herself was okay, but others taunting her about her lack of wings or being "too big" to be fae was not. ]
People love puttin' an evil label on that which they don't understand, whether you're a vampire, witch, faerie, werewolf, or whatever happens to not be human.
