For Nancy: If it's hot enough, all you'd need to rock is a blond wig, an orange bikini, and smears of fake blood (don't forget the shark bite on her leg!). Otherwise, get yourself a wet suit (or black yoga pants and a tight black long-sleeved shirt you can cut down the middle), and wear your bikini under it. If you can carry around a mini version of her surfboard with a big shark bite on it, you'll be golden.
