Hooray for Hollywood! In addition to the Zone diet, lip injections, over-sized sunglasses, and the Arquettes, Hollywood has given us movies. Where better to search for costumes than in the land of make-believe? And who better to inspire you for the creepiest of holidays than Alfred Hitchcock. Yup, that’s Tippi Hedren from “The Birds” and Norman Bates from “Psycho.”

Want to cross-dress without getting scary? There’s always “Hairspray.” If it’s good enough for Travolta . . .

Of course, if you’re looking to tune in to your inner Travolta, you can always go for his “Saturday Night Fever” look, or you could be Danny from “Grease.” Plus, wasn’t he an angel once? “Michael,” maybe? In fact, you could have an entire John Travolta-themed party, where everyone dressed as one of his characters!!!! Or not.

Next up, scary movies! Okay — more scary movies. I already did Hitchcock. But frankly? I’m busy here and don’t have time for that thing known as “organization.”

“Nightmare on Elm Street”: Freddy Krueger never gets old. (Actually, he does.) Way more original: “A Nightmare Before Christmas.”

Don’t forget about kids movies: “Toy Story,” “The Incredibles,” “The Wizard of Oz,” any classic Disney film. And don’t be afraid to add your own twist. I, for one, would love to see Ariel the little mermaid gone bad.
