Tonight is the biggest party of 2015: The Metropolitan Museum's Costume Institute Gala, or the Met Gala for short. This year's evening kicks off the China: Through The Looking Glass exhibit, which looks at how fashion has been inspired by China (or just appropriated Chinese culture). And it's safe to say that Rihanna killed the red carpet.

The singer appearing wearing a yellow gown with a long train (it appears to be 5% dress, 95% train) by Chinese haute couture designer Guo Pei. The designer, who is based in Beijing, has two dresses in the show—one took her 50,000 hours to complete, and the other took her 10,000 hours.

In terms of drama, the runner-up award is split between Sarah Jessica Parker, who wore an H&M gown along with a Philip Treacy headdress (Treacy designed Princess Beatrice's extremely viral 2011 fascinator) and Beyonce, who arrived last in a sheer gown with strategically placed gems.

The dress code is of course high fashion for ladies but the men were confused by requests for "Chinese white tie." We're not sure if Larry David has passed muster (yes, for some reason he's there!).

Click through for photos of Anne Hathaway, the Olsen twins, Justin Bieber (or Kate McKinnon), Kim and Kanye, Jennifer Connelly and many others.

China: Through the Looking Glass will run from May 7 through August 16.
