Arguably the most important event on the fashion calendar, the Costume Institute Gala - better known as the Met Gala - is an annual banquet that takes place on the first Monday in May at the Metropolitan Museum of Art in New York City.

Each year brings a different theme, one that aims to challenge and inspire the A-list stars in attendance. From religious iconography to futuristic headpieces, attendees are dared to commit to being as extra as possible as they climb the iconic staircase to meet their host, Vogue editor-in-chief, Anna Wintour. 

Inspired by Susan Sontag’s 1964 essay, Notes on ‘Camp', this year's theme - and accompanying exhibition - is Camp: Notes On Fashion. The exhibition features approximately 250 objects, including womenswear and menswear, sculptures, paintings, and drawings dating from the 17th century to the present.

In her essay, Sontag described 'camp' as "a vision of the world in terms of style - but a particular kind of style. It is the love of the exaggerated, the "off," of things-being-what-they-are-not."

To put it simply, the event's co-chairs -  Anna Wintour, Lady Gaga, Alessandro Michele, Harry Styles, and Serena Williams - asked that their guests serve the most exaggerated and fabulous looks possible. And, oh my, did they deliver.

The highlights...

Cardi B Met Gala 2019
Cardi B wore Thom Browne

Cardi B wore a breathtaking oxblood Thom Browne gown. Made from silk organza and tulle, the show-stopping dress is approximately ten feet long. Decorated with 30,000 dyed coque feathers, it is reported that the dress took 35 people to make it.

Celine Dion brought a little bit of Las Vegas to the city that never sleeps, wearing a showgirl-inspired Oscar de la Renta ensemble.

Lady Gaga wore not one, not two, not three, but four incredible custom made costumes by Brandon Maxwell. In a jaw-dropping entrance, the singer walked the steps of the Met along with five dancers, a makeup artist, and her personal photographer to capture the performative entrance. Let's be honest, Gaga was in her element.

Billy Porter made quite the entrance wearing a look by The Blonds, shoes by Giuseppe Zanotti, and jewellery by Oscar Heyman, Andreoli, John Hardy, and Mordekai. Oh, and did we mention the six shirtless men that carried him in? Now that's camp, darling.

Girls stars Jemima Kirke and Lena Dunham wore co-ordinated Christopher Kane ensembles. Jemima's dress has "Looner" written across it, a popular term for those with a balloon fetish, while Lena's dress says "Rubberist", a term for those with a fetish for wearing rubber.

Jared Leto wore Gucci and carried an unusual accessory...

Katy Perry shone in a Moschino chandelier dress.

Bibbidi-Bobbidi-Boo! Zendaya brought a pinch of magic to the pink carpet with her Disney-inspired gown. Zenderella shall go to the ball!
