The theme of this year’s Met Gala is “China: Through the Looking Glass,” so the stars will probably wear garments that honor Chinese heritage.

Those who have the app Periscope can view the 2015 Metropolitan Museum of Art’s Costume Institute Gala, which is better known as the Met Gala, online. Periscope, for those who don’t know, is a live video streaming app that can be used on iOS. It was created by Kayvon Beykpour and Joe Bernstein and garnered attention after Twitter bought it for a reported $100 million in the beginning of 2015.

To watch the live stream, head over to the Twitter page for the Metropolitan Museum of Art, where they’ve provided their Periscope username. To catch all the fun, iOs users should make sure they log in to Periscope at 6 p.m. EDT.

The Met Gala raises money for the museum and also marks the grand opening of the Costume Institute’s annual fashion exhibit.

Oscar-winner Jennifer Lawrence leads the list of event co-chairs, which includes fellow actress Gong Li, Yahoo CEO Marissa Mayer, Wendi Murdoch and Vogue editor, Anna Wintour, after whom the Met’s Costume Center is named. The evening’s chair is Silas Chou, the Hong Kong fashion and textiles billionaire, whose holdings have included Tommy Hilfiger and Michael Kors.

Other celebrities expected to attend include Anne Hathaway, Beyoncé, Benedict Cumberbatch, Bradley Cooper, Cara Delevingne, Dakota Johnson, Jennifer Lopez, Kanye West, Kate Hudson, Katy Perry, Kendall Jenner, Lupita Nyong’o, Matthew Broderick, Neil Patrick Harris, Sarah Jessica Parker, Sienna Miller and Reese Witherspoon.
