The Met Gala 2019

Lady Gaga, one of this year's co-chairs for the Met Gala, just arrived in a theatrical, billowing fuchsia gown by Brandon Maxwell.

The train was carried by a number of tuxedo-wearing men with black umbrellas.

After parading up and down the Metropolitan Museum of Art's stairs, Gaga stripped the gown off to reveal a strapless black dress underneath and posed with one of the umbrellas.

But she wasn't done.

Gaga then took off the black dress to reveal another pink dress — this one form-fitting — underneath. She put on extra-large black sunglasses and carried a brick-like phone.

And after that, she stripped down to her underwear and kneeled and posed on the stairs.

Vogue editor-in-chief Anna Wintour is wearing feathers at the Met Gala tonight.

Wintour told CNN’s Christiane Amanpour last month that she planned to take inspiration from a line in Susan Sontag’s essay, "Notes on 'Camp'" for her own attire tonight.

Sontag writes in the essay: “Camp is a woman walking around in a dress made of three million feathers.”

Wintour has transformed the Met Gala into a night of Oscar-level red carpet excitement and serious fundraising.

In 2015, the New York Times reported that the gala had raised over $145 million under Wintour, a figure that will likely surpass $200 million after tonight’s event.

On this year’s “camp” theme, Wintour said that the team was referring to “camp” as “from sun kings to drag queens” in-house.

Watch for more:

If this year's fashion at the Met Gala is anything like past events, A-listers and Hollywood stars will likely don extravagant and show-stopping gowns.

Here's a look at last year's red carpet:

The biggest names to attend the Met Gala are A-list models, musicians and actors, though occasionally a megawatt outsider will get pulled into its orbit.

Filling the rest of the seats (only about 600 people were invited in 2015) are brand representatives, emerging designers, and invited patrons happy to spend upwards of $30,000 for a ticket. But this hasn't always been the case.

"Yes, it was great hanging out with Tina Chow and Andy Warhol, but the highlight was seeing a very young Miss J (yes, from 'America's Next Top Model') vamping into the Temple of Dendur in full drag."

Anna Wintour, Vogue's current editor-in-chief, shifted the focus to celebrities when she took over as chairwoman in 1999, recruiting A-list honorary chairs and co-chairs.

This year's co-chairs are...

New York's Metropolitan Museum of Art will soon open its doors for the Met Gala, the annual invitation-only fundraiser to benefit the museum's Costume Institute, and a launch party for its spring exhibition.

Here's what you need to know about fashion's biggest night:

This year’s Met Gala and accompanying Costume Institute exhibition is entitled "Camp: Notes on Fashion."

The 2019 show looks likely to be the most outrageous to date, with the theme drawing on a 1964 Susan Sontag essay that describes camp as "love of the unnatural: of artifice and exaggeration.”

Fun fact: A total of 250 objects, including womenswear and menswear from the 17th century to the present will be on show at the Costume Institute exhibition.

Parts of the show will demonstrate how the royal courts of Louis XIV and Louis XV embraced the concept of camp, an exploration of how dandies demonstrated the "camp ideal," and camp's origins in European and American queer subcultures in the late 19th and early 20th centuries. The works of Donatella Versace, Marc Jacobs, Jeremy Scott and dozens of others will be featured.

Our red carpet coverage starts at 7 p.m. ET.
