For celebrities, the annual Met Gala is a chance to show the world how famous, fashionable and flamboyant you are.
For the rest of us, it's a chance to watch extremely attractive people wearing their own weight in diamonds and feathers.
The Met Gala is held every May in New York to celebrate the opening of the Metropolitan Museum of Art's latest exhibition, with guests asked to dress to match the theme.
This year's exhibition is Camp: Notes on Fashion and guests were encouraged to be as theatrical and colourful as possible.
"The hallmark of the camp is the spirit of extravagance. The camp is a woman walking around in a dress made of three million feathers," US philosopher Susan Sontag wrote in her 1964 essay Notes On Camp.
