It's almost time for fashion's biggest night of the year: the 2023 Met Gala.
Every year the glamorous event at The Metropolitan Museum of Art in New York City brings together celebrities, like Kim Kardashian and Blake Lively, in over-the-top outfits based around a costume theme.
This year the theme is getting a lot of heat prior to the gala because it's based on the late designer Karl Lagerfeld.
From the theme to the hosts and much-anticipated guest list, here's everything we know about what you can expect at the 2023 Costume Institute exhibition.
What is the Met Gala?
The Met Gala is an annual celebration of fashion and has been organized by Anna Wintour since 1995, as per a report by Vogue.
The charity event raises money for the Metropolitan Museum of Art’s Costume Institute and also marks the opening of its annual fashion exhibit.
Entertainment Tonight says last year's event raised $17.4 million for the exhibit. The outlet also revealed that tickets to event start at $50,000.
According to Vogue, the event is a phone-free event, meaning guests are not allowed to use their phones while they're at the Met Gala. The event also has a big name performer and guests get to take in the exhibit before they have dinner.
What is the theme for the 2023 Met Gala?
The theme for this year's Met Gala is Karl Lagerfeld: A Line of Beauty and will celebrate the work and life of the late German designer, according to Vogue.
Lagerfeld, who died in 2019, was a well-known designer who worked for many high-end labels, including Chanel, Fendi, Balmain and Chloé, as well as his own namesake brand.
This year's theme is a controversial one due to Lagerfeld history of comments that were often labelled either racist, fatphobic, or misogynistic.
According to the Washington Post, in 2012 the designer called singer Adele a "little too fat," which he later apologized for.
The outlet also points out that in a 2009 interview with the German magazine Focus, Lagerfeld made a comment that no one "wants to see" plus-size models.
“You’ve got fat mothers with their bags of chips sitting in front of the television and saying that thin models are ugly,” he said, according to the Washington Post.
The Post also included a comment that Lagerfeld made in a 2018 interview with the European magazine Numéro. In it, he made comments about the MeToo Movement saying that he was "fed up" with it and called out all the "starlets who have taken 20 years to remember what happened."
When the theme was revealed in late 2022, actor and activist Jameela Jamil announced on she would not be attending and denounced Lagerfeld's “distinctly hateful” comments “mostly towards women.”
