Don't Miss:

For “A Crowd of Demons,” 666 Park Avenue’s special Halloween episode, airing tonight at 10 p.m. EST on ABC, Rachael Taylor’s Jane Van Been dresses up as Tippi Hedren’s Melanie Daniels, the victim in one of Alfred Hitchcock’s most iconic films, The Birds. Her costume—a celadon green wool crepe dress with black birds wired and sewn into it—was the handmade creation of costume designer Caroline Duncan. “This is definitely the scariest episode we’ve made,” Duncan told InStyle.com. “It’s an homage to Hitchcock, the greatest horror filmmaker ever. And what’s happening with Rachel’s costume is very tongue-in-cheek—she’s been haunted by birds ever since she moved into the building.” The costume is the result fastening and readjusting the birds to sit just right on Rachael’s frame. “Once the dress was done, we played with a lot of styles and sizes of birds,” Duncan said. “The birds are actually lawn decorations from Pottery Barn! We spent a lot of time manipulating them; they all come in one shape, and we sort of tweaked the wings.” Fun fact: The bird on her wrist, Duncan told us, actually doubles as a handbag! Tune in tonight to see the amazing costume in action!
