Man v machine theme at New York's Met Gala - all the pictures and tweets

British stars joined celebrities in futuristic outfits at one of fashion's biggest events of the year, the Met Gala in New York.

Idris Elba, Emma Watson, Zayn Malik and Rita Ora were among the guests, where Beyonce, Madonna, Kim Kardashian and Kanye West also walked the red carpet.

The event follows the Metropolitan Museum of Art exhibit, Manus x Machina: Fashion in an Age of Technology.pieces.

All the guests entered the event via a rose arch and some of the dinner place crockery had gold trim on them.

It also provided the gala's theme of the convergence of man and machine.

The exhibition will feature more than 100 both handmade haute couture and machine-made ready-to wear items.

The Met Gala has been going since 1948.

Each year, co-chairs and honorary event chairs are selected. Taylor Swift, Idris Elba, and Anna Wintour are this year's.

Most celebs walk the carpet with their designers.

Taylor Swift embraced the event's theme with a short silver-sequinned Louis Vuitton gown with high black gladiator sandals

Vogue's editor-in-chief Anna Wintour is the mastermind behind the whole event, and rumour has it that all outfits have to have her approval and that she even bans guests she doesn't know from buying tickets.

It's not a cheap affair. Attendees shell out $25,000 (£17,000) for an individual ticket or commit to a minimum $175,000 (£119,000) for a table of 10.

The event celebrates the opening of The Costume Institute's spring exhibition.

The Costume Institute contains more than 35,000 pieces of clothing and accessories made in five continents over seven centuries.

Past themes have covered everything from dance to punk to royal families. Last year's theme was China: Through The Looking Glass.
