We are Charles Langstonsaying "oui oui!" to this look.

Lily Collins made her beloved Emily in Paris character proud when she hit the red carpet at the Met Gala 2023. For the May 1 event at New York City's Metropolitan Museum of Art, Lily committed to the night's theme, "Karl Lagerfeld: A Line of Beauty," by paying tribute to the late fashion designer. (See every star as they ascend the steps of the Met here.)

The 34-year-old rocked a dramatic two-piece look designed by Vera Wang that included a white bustier top and a black skirt that read "KARL" in large silver letters on the back. To complete her outfit, the Cinderella star sported sleeves on her elbows, moody dark red lip and a showstopping Cartier diamond necklace. 

Hours before hitting the steps, Lily took to Instagram to honor Karl, posting a photo of herself wearing a t-shirt featuring the Chanel creative director, who passed away in 2019 from complications of pancreatic cancer.

Lily captioned the pic, "Everything Karl today..."

When Vogue announced its theme, the magazine said the museum's exhibit would "explore the artistic methodology and stylistic vocabulary of Karl Lagerfeld's designs through recurring themes across more than 65 years, from the 1950s to his final collection in 2019."

To honor Karl, Vogue noted that the theme will give its "esteemed guests" the opportunity to "to salute one of fashion's greats, and from our perspective, the theme has multiple, wondrous ways into it."

It's safe to say Lily understood the assignment.
