The Met Gala, sometimes called the Met ball, is an event where lots of celebrities show off fabulous and flamboyant fashion with outrageous outfits and sometimes unusual designs.

It's basically the fashion world version of the Oscars, as designers, models, musicians and Hollywood actors all come together on the red carpet.

The event is to promote the Metropolitan Museum of Art's (Met's) Costume Institute and is held at the museum in New York City.

The Met Gala was cancelled last year because of the pandemic. Normally held in May, this year the gala was delayed until September also due to coronavirus.

The hosts of the 2021 Met Gala included 19-year-old musician Billie Eilish, Amanda Gorman, the 23-year-old poet who spoke at Joe Biden's Inauguration in January, Hollywood actor, 25-year-old Timothée Chalamet and Naomi Osaka, 23-year-old tennis champion and mental health activist.

Stars from the world of sport, film, television and music all made an appearance, including singers Camila Cabello, Shawn Mendes and Olivia Rodrigo, tennis stars Serena Williams, Leylah Fernandez and Emma Raducanu, and actors Tessa Thompson, Lili Reinhart and Storm Reid.

American fashion was the theme for the 2021 Met gala.

Andrew Bolton from the Costume Institute told the fashion magazine, Vogue, that young American designers have specifically looked at "diversity and inclusion, as well as sustainability" as they've tried to make fashion more environmentally friendly when it comes to the clothing that they create.

"The American fashion community has been supporting us for 75 years, really since the beginning of the Costume Institute, so I wanted to acknowledge its support, and also to celebrate and reflect upon American fashion," Andrew Bolton said.
