What was once solely a fundraiser for the New York Metropolitan Museum of Art's Costume Institute, the first Monday in May has evolved into one of the biggest events on Hollywood's social calendar.
There is months of preparation, an exclusive guest list vetted by Anna Wintour and, of course, after-parties to follow.
But that doesn't mean the night isn't without controversy.
From Elevatorgate to the Marilyn Monroe dress fiasco, here we look back at some of the most controversial Met Gala moments (so far).
But first, watch: the wildest Met Gala looks of all time. Post continues below.
Elevatorgate: Jay-Z, Beyoncé and Solange.
At the 2014 Met Gala, there was one story that made headlines everywhere.
Surveillance footage from the night was leaked, showing an altercation between Beyoncé's sister Solange and Jay-Z in an elevator. The footage showed Solange repeatedly lunging at Jay-Z. Beyoncé stood aside and watched the altercation, before eventually stepping in between the two.
Solange didn't face any charges over the matter.
The family soon after released a statement, saying Jay-Z and Solange had "worked through it".
