Many royal fans will be dressing up as Queen Elizabeth, Meghan Markle and Kate Middleton this holiday, but even a duchess has a few Halloween costumes in her closet!

Before she married Prince William and became the Duchess of Cambridge, Kate celebrated Halloween 2007 by attending a party with her younger sister, Pippa Middleton. The soon-to-be royal wore a black dress paired with a black cape, fishnet stockings and boots, making her a spooky character (perhaps a glamorous vampire or bewitching witch?) for the night out.
