What to wear: Sarah's got that definite grunge vibe going, at least when the series starts. She obviously softens it up to become Beth, but this is the Sarah we all know and love. Pair a black leather jacket with a striped shirt, dark tights, shorts, and heavy boots. Go heavy on the eye makeup and the ratty hair.
How to act: Don't be afraid to be a little tough and abrasive. Sarah's a good person, but she's definitely rough around the edges. In a good way.
