The worlds of fashion, celebrity, music, business and sports will collide tonight at the 2023 Met Gala, where attendees pay tribute to late German fashion designer Karl Lagerfeld.

Considered one of the most extravagant annual events in the entertainment industry, the Met Gala is a yearly fundraiser for the Metropolitan Museum of Art's Costume Institute.

Guests are expected to dress in theme with the museum's yearly exhibit. This year's theme, Karl Lagerfeld: A Line of Beauty, pays tribute to an industry legend with a complicated legacy.

Reality star Kim Kardashian, rapper Lil Nas X and actor Anne Hathaway were among those on the carpet.

Lagerfeld, who died in 2019, was celebrated for his contributions to fashion. In addition to his own eponymous couture line, he was the creative director of French fashion house Chanel and of Fendi, the Italian fur and leather luxury line.

He has long been criticized for making remarks that were sexist, racist and fatphobic in nature. Lagerfeld criticized the #MeToo movement and made derogatory comments about plus-sized models on several occasions.

As such, the theme has invited backlash, including from the Met Gala's social media team, which has opted not to live-tweet this year's proceedings in protest.

Guests who dress on theme might choose designs inspired by Lagerfeld's collection, as well as pieces from Chanel or Fendi. They might also replicate his own signature style: a shock of white hair, high collars, sunglasses and fingerless gloves.

Vogue editor-in-chief Anna Wintour co-chaired this year's event, as she has since the 1990s. Her co-chairs this year are Oscar winning actor Penélope Cruz, Ghanaian-British actor and writer Michaela Coel, tennis star Roger Federer and pop singer Dua Lipa.

Dua Lipa wore a Fall 1992 Chanel wedding dress designed by Lagerfeld.

"It's been on my mood boards forever, and when the opportunity came I was like, is there any way I can find this dress?" Lipa said on the carpet.

Cruz, also wearing a vintage bridal gown, said she was inspired by Chanel's Spring 1988 collection.

Supermodel Naomi Campbell wears a baby pink gown draped from the shoulders with silver detailing.

Model Anok Yai wears a corset dress with gold and silver sequins and a black train.

Model Suki Waterhouse wears a nude dress with floral embroidery and The Batman actor Robert Pattinson wears a partially pleated navy Dior suit.

Succession star Jeremy Strong wears a frilled, seafoam green shirt with a yellow tie and a chocolate brown overcoat.

Actor Brian Tyree Henry wears a multi-piece suit paired with a dramatic black cape and layered necklaces.

Rapper Doja Cat wears a curious ensemble, a likely nod to Lagerfeld's beloved cat, Choupette: a sparkling hooded gown with cat ears, a pendant resting on her forehead and a prosthetic cat nose.

Actor Gabrielle Union and former NBA player Dwyane Wade wear complementary leather looks, she in head-to-toe red and he in all black.

Jared Leto arrived to the event wearing a cat mascot costume — again inspired by Choupette — before changing into an all-black suit with a cape and silver epaulettes.

Everything Everywhere All At Once actor Ke Huy Quan channels Lagerfeld's personal style in a pinstripe suit, fingerless gloves and dark sunglasses.

Actor Jeremy Pope wears a sprawling white cape with Lagerfeld's face printed on its surface in black and white.

Rapper Sean "Diddy" Combs wore a black studded jacket and a cape adorned with rose-shaped appliques, designed by his own fashion label, Sean John.

Canadian NBA player Shai Gilgeous-Alexander wears a short checkered jacket and matching skirt with pearl strings, a bowtie and a cummerbund.

Well, it happened: actor-turned-director Olivia Wilde and Vogue China editor-in-chief Margaret Zhang both wore the famed "violin" dress designed by Lagerfeld for fashion house Chloé, albeit in different colours.

French fashion designer Olivier Rousteing seemingly made a statement with a handbag bearing the words "Karl Who?" on it. The accessory is, in fact, similar to a tote bag that Lagerfeld once carried.

South Korean model Sara Choi sports a bold red lipstick and an elaborate bouclé pantsuit paired with a dark, polka dotted jacket-cape.

Rapper Erykah Badu wears a white dress with a cowl neck and fringed hood, accessorizing with blue opal and golden jewelry.
