The Met Gala 2019

Harlem-based designer Dapper Dan, who's currently collaborating with Gucci, hit the red carpet in a red jacket embroidered with light blue flowers.

He dressed many of tonight's guests, including model Karlie Kloss, who is in a super-short mini dress featuring statement puff sleeves.

Some background about Dapper Dan: He outfitted a generation of gangsters, rappers, and athletes by putting high fashion logos onto bespoke pieces more tailored for the streets. His Harlem store was shut down in the early '90s after the houses whose logos he pulled without authorization took notice.

Fast forward to 2017, when Gucci was being called out for ripping off one of his bootleg designs, leading to an official collaboration, and the Italian house backing his own atelier.

Singer Harry Styles donned a flamenco-inspired, gender-fluid look designed by Gucci at tonight's Met Gala.

Styles walked the red carpet with Gucci creative director Alessandro Michele.

Styles, member of the pop group One Direction, is one of the event's co-chairs.

Actress Laverne Cox's camp-inspired outfit tonight is by Christian Siriano.

Her black gown included a dramatic ruffled shoulder piece and black sequins down the front. The gown's train is ruffled, too.

Lady Gaga wasn't the only dramatic Met Gala arrival. Enter Billy Porter.

The actor was carried onto the red carpet by six shirtless men, who wore gold pants and headpieces.

His Ancient Egypt-inspired outfit included a gold jumpsuit with wings and a gold crown. His makeup is by British make up artist Pat McGrath.

Tennis superstar Serena Williams was a ray of sunshine at this year's Met Gala.

She strutted into the event at the Metropolitan Museum of Art wearing a pair of neon yellow Nike Air shoes made in collaboration with Off-White, and a voluminous fluorescent yellow Versace gown dotted with pink leaves.

Williams is one of this year's Met Gala co-chairs.

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.
