On Tuesday night at the Museum of Modern Art New York City, stars including Demi Moore, Naomi Watts, Calista Flockhart and Molly Ringwald got glammed up for the black-and-white carpet premiere of their new Ryan Murphy project for FX, Feud: Capote vs. The Swans. The story is based on a real-life drama, when Truman Capote (played by Tom Hollander) tanked his own social circle by writing an exposé on his powerful and privileged friends. The so-called society "Swans" quickly cut him off and put a target on his back. The cast is all-star, with Flockhart as Lee Radziwill, Chloë Sevigny as C.Z. Guest, Diane Lane as Nancy "Slim" Keith, Ringwald as Joanne Carson, Naomi Watts as Babe Paley and Demi Moore as Ann Woodward. Here, see all the women arriving at Tuesday night's black and white-themed premiere — and what they wore. And catch the series when it debuts on FX on Jan. 31 at 10 p.m. ET. 01 of 20 Demi Moore Demi Moore.
