Rihanna, Taylor Swift and Sarah Jessica Parker were among the stars who stepped out at the Metropolitan Museum of Art's Costume Institute Gala in New York.
Trains were the trend of the night with Sex And The City star SJP wearing a black-and-white Oscar de la Renta gown, that included the designer's signature on the back of her dress, while Taylor looked pretty in pink, also in an elaborately embroidered Oscar de la Renta number.
The I Knew You Were Trouble singer admitted her outfit didn't go down too well with her pet, tweeting before the bash: " That moment when your cat casually walks up, then abruptly ATTACKS your custom satin Oscar de la Renta gown during your fitting for Met Ball."
Cropped outfits were also popular on the red carpet for the annual star-studded event, which is one of the biggest nights in the New York fashionista's calendar.
Rihanna turned heads in a white backless two-piece creation by Stella McCartney, while Cara Delevingne flashed her belly button in Stella McCartney's black ribbon top and white trousers.
Anne Hathaway kept it rather safe, barely baring her belly in her red Calvin Klein Collection two-piece gown with a structured bodice and slit skirt, as Emma Stone wore a pink and red Thakoon top and skirt ensemble.
Rita Ora looked every inch the golden goddess in Donna Karan Atelier, while Glee star Lea Michele dazzled in Joseph Altuzarra.
12 Years A Slave star Lupita Nyong'o lived up to her adventurousness with a customised feathered and beaded Prada creation, while singer Erykah Badu could have given Pharrell Williams a run for his money with her jewelled Givenchy hat.
Katie Holmes' mustard gown failed to impress, as did Shailene Woodley's Rodarte dress.
This year's gala, titled Charles James: Beyond Fashion, was a tribute to the late British-born designer Charles James, known as America's First Couturier. Vogue editor Anna Wintour chaired the glitzy event, alongside Bradley Cooper and Sarah Jessica Parker.
