In the 2004 film, Mean Girls, Cady (Lindsay Lohan) is invited to a Halloween party. Previously homeschooled, Cady dresses as a zombie bride, but is shocked to find her peers wearing much more suggestive costumes. “In girl world”, Cady muses, “Halloween is the one time a year when a girl can dress like a total slut, and no other girls can say anything about it.”
One of those girls, Regina George (Rachel McAdams), is wearing one of the most culturally significant costumes of the last decade: the Playboy bunny suit.
