Celebrities and noted figures from the fashion world turned out for one of the biggest events of the year Monday night: the Met Gala, held at the Metropolitan Museum of Art in New York City.
The event was hosted by Chinese billionaire Silas Chou. Vogue editor-in-chief Anna Wintour is in charge of the exclusive guest list each year.
This year, Yahoo CEO Marissa Mayer, Jennifer Lawrence, Wendi Deng, and Gong Li served as co-chairs.

She once paid $60,000 to have lunch with de la Renta and has said the late designer's three-quarter cashmere cardigan has become her work uniform - she owns one in ivory, navy, black, hot pink, teal, red, and royal blue.
Yahoo co-sponsored the event. Though it's unknown just how much the company paid to be a sponsor, past event sponsors have paid as much as $1 million, sources told the New York Times.
Hosting the Met Gala gave Mayer the opportunity to build stronger relationships within the fashion community.
Still, she's not the first tech exec to do so - Jeff Bezos served as co-chair in 2012, shortly before launching Amazon's venture into high fashion.
The Winklevoss twins also attended last night's event, as did Instagram CEO Kevin Systrom.
Systrom, who recently traveled to Paris to meet with fashion executives, wore a white ensemble by Ralph Lauren.
