There are two sisters, close enough in age to have a relatively equal relationship, but light years apart in personality. * The Beautiful Sister: A pretty, extroverted, fashionable popular but unintellectual character. If older (and she usually is), she'll be more mature in "womanly" ways. Can range from smart yet Book Dumb to The Brainless Beauty. Endlessly criticises her sister for her willing social outsiderness. * The Smart Sister: A bookish, explicitly smart character - often Hollywood Homely. Very often a Deadpan Snarker and The Snark Knight. Subject to far less male attention. Endlessly criticises her sister for her willing shallowness.
