The Met Gala –also known as The Met Ball or “fashion prom” — took place Monday at the Metropolitan Museum of Art.

The annual fundraiser’s theme this year was “China: Through the Looking Glass.” Guests were encouraged to dress in theme.

Chinese billionaire Silas Chou was this year’s host of the $US25,000-a-ticket affair, while Jennifer Lawrence, Marissa Mayer, Wendi Deng Murdoch, Gong Li, and Anna Wintour served as co-chairs.

But it is Wintour who has overseen the star-studded guest list since 1995.

This year’s A-list attendees include: Rihanna, Kim Kardashian, Kanye West, Madonna, Katy Perry, Sarah Jessica Parker, Reese Witherspoon, Sofia Vergara, Ivanka Trump, Allison Williams, and many more.

Vogue editor-in-chief Anna Wintour, chair of the event since 1995, arrived in vibrant red Chanel couture.
