Watch 'The First Monday in May' trailer: Fashion's new must-see documentary

The Met Ball, held by the Metropolitan Museum of Art, is the yearly event every who's who of the fashion, music, art and film world wants to be at. Last year's gala entitled 'China: Through the Looking Glass' was one of the biggest yet - and luckily, for us that missed the guest list, a documentary was made. Filmmaker Andrew Rossi followed Anna Wintour, Vogue Director of Special Projects Sylvana Ward Durrett, and Metropolitan Museum of Art’s Costume Institute curator Andrew Bolton to create The First Monday in May. The second Vogue-centered documentary after the success of 2009's The September Issue. The new documentary also gives a behind-the-scenes look at the incredible party - including some of Bad Gal Riri's incredible performance. The First Monday in May will open the Tribeca Film Festival on April 13.
