Madonna, Kate Moss, Victoria Beckham and Anne Hathaway were among guests at yesterday's Metropolitan Museum of Art Costume Institute Gala in New York.
The event, which served as the launch to the museum's The Model as Muse: Embodying Fashion exhibit, was hosted by Vogue editor Anna Wintour and co-chaired by Kate Moss and Justin Timberlake.
Madonna, 50, stunned onlookers at the gala evening by donning thigh-high boots and a tiny blue ruffled dress topped with a bizarre headpiece.
Only Gossip Girl star Leighton Meester made a worse choice, shunning a pretty gown for a garish printed jumpsuit.
Moss embraced the Greek theme by donning a daring toga-inspired metallic dress and head piece.
She was accompanied on the red carpet by the frock's creator Louis Vuitton designer Marc Jacobs, who chaired the evening - regarded as the biggest night on the fashion calendar.
Beckham also won praise for her Louis Vuitton outfit, a cute polka-dotted minidress with a long sweeping train which showed off her toned back and legs.
Hathaway opted for a short dark purple Marc Jacobs 80s-style gown, while many other stars - including Katy Perry, Blake Lively and Claudia Schiffer - opted for blue.
Jessica Biel showed her devotion to boyfriend Justin Timberlake by wearing a flowing Spanish-style red dress from his William Rast clothing line, while Eva Longoria and husband Tony Parker opted for matching black.
Pregnant model Heidi Klum's lavish J Mendel sweeping gown reportedly took over a month to make, while Liz Hurley's peach Estee Lauder frock was a similar full-length, full-skirted style.
Stella McCartney was well-represented, with friends Kate Hudson, Kate Beckinsale and Liv Tyler - who joked she had been "forced" into wearing her gown - choosing her creations.
Other stars at the event included Rihanna, Kanye West, Rachel Weisz, Cindy Crawford, Kirsten Dunst, Bono, Tyra Banks, Mary-Kate and Ashley Olsen, Eva Mendes and Renee Zellweger.
Rihanna arrived in black - including both the SUV and her Dolce and Gabbana suit and bow tie. It was her first such appearance since then-boyfriend Chris Brown allegedly beat her in February.
She was the last celebrity to walk the carpet and did not speak with press.
