In a stunning Oscar de la Renta dress that cost $17,990 at Oscar de la Renta, Taylor Swift walked the red carpet at the New York City opening of Cats on Monday night and looked stunning.

The movie is a musical fantasy comedy-drama based on Andrew Lloyd Webber’s stage musical of the same name. Taylor also co-wrote the new song “Beautiful Ghosts” for the soundtrack.

She plays the part of Bombalurina in the movie, a flirty, sure-of-herself female cat with a bright red coat.

The song was nominated for a Golden Globe. In the movie, Francesca Hayward plays the lead character Victoria, who sings it. The Academy recently said, though, that it will not be getting an Oscar nod.

The singer and actress, 30, wore Chloe Gosselin’s Narcissus shoes with her flower ball gown. She also wore Maxior drop earrings and rings by Borgioni and Beladora.

That’s how you say “cut threads” in French: fil coupé. The company Greenhouse Fabrics says that this “weaving technique creates a delicate yet tactile fringe effect on the fabric’s surface.”
