6. Sookie Stackhouse from Tru Blood. Anna Paquin’s getup as Sookie Stackhouse is hardly scary in the traditional sense – but we love this costume for its ironic sweetness. Get Sookie’s sweetly curled low ponytail with a pair of curling tongs and you’re ready to go. For a variation, try Sookie’s ‘thin headband’ look. For her makeup, keep it simple and add just a little black eyeliner on the top and bottom lashes. You can buy the Merlotte’s waitress costume direct from the HBO online store.
