The Met Gala, formerly the 'Costume Institute Gala' or 'Met Ball', is a firm fixture in the fashion calendar. This year's theme is a tribute to Karl Lagerfeld - Karl Lagerfeld: A Line of Beauty - while co-chairs include the all-star line-up of Michaela Coel, Penélope Cruz, Roger Federer and Dua Lipa.
Conceived as an annual fundraiser for the Metropolitan Museum of Art's Costume Institute, it marks the opening of the institute's annual fashion exhibit and also plays host to a series of jaw-dropingly spectacular outfits. Famous for being the fashion industry's equivalent of the Oscars, the gala is known for being a who's who of Hollywood (and beyond). Such stars include Kim Kardashian, Kate Moss, Beyoncé, Billie Eilish, Lady Gaga, Rihanna and of course, Anna Wintour – chair of the event and guardian of the guest list.
Scroll down to remember some of the best – and most daring – looks in recent history.
