The Met Gala has been running annually since 1965 – with the exception of 2020 due to Covid lockdowns.
Since 1995, the gala has been chaired or co-chaired by Vogue editor Dame Anna Wintour, one of the most powerful and influential figures in fashion.
The purpose of the gala is to raise money for the Costume Institute, the fashion wing of the Metropolitan Museum of Art.
But the Met Gala is primarily seen as a highly exclusive social event, as well as the biggest night in the fashion calendar.
A magnet for A-listers, the gala has wider reach than ever in the age of social media, as fans pore over the outfits – with the most outlandish ones often going viral.
Regular attendees include Kim Kardashian, Rihanna, Lady Gaga and Billie Eilish.
This year, Zendaya, Jennifer Lopez, Bad Bunny and Chris Hemsworth are co-chairs of the event.
