Sam Smith made 'a statement of inclusion' in an anti-Barbiecore look on the red carpet

• Smith wore an oversized sweater by Vetements and jeans to the "Barbie" premiere in London.
• While "Barbie" cast members have been embracing pink, Smith rejected the Barbiecore trend.

Margot Robbie has been wearing one Barbie-inspired outfit after another in the lead-up to the July 21 release of the "Barbie" movie.

But not everyone involved in the film is embracing pink.

Sam Smith rejected the Barbiecore trend at the European premiere for "Barbie" on Wednesday.

The musician, 31, walked the pink carpet at London's Leicester Square in oversized jeans and a baggy navy sweatshirt with "16 XL" printed across the chest from Vetements' spring/summer 2024 collection, according to an Instagram post shared by the designer.

Smith was at the premiere to promote their new single, "Man I Am," which will appear on the movie's soundtrack when it's released on July 21. The song was written from Ken's perspective, Smith wrote in an Instagram post about their involvement in the film.

Smith posted several photos of the outfit on Instagram alongside the caption: "Thank you @gvasalia & everyone at @vetements_official for making me feeling sexy and XXL last night." Smith tagged Guram Gvasalia, creative director of Vetements, in the post.

"16 XL BARBIE," Smith captioned another post that included photos from the event.

Smith's outfit was 'a statement of inclusion'

In an interview with Harper's Bazaar about Smith's outfit, Gvasalia said "Sam is so unique and unexpected, that pink and fluffy would have been too easy."

"It's not only the outfit, it's a statement of inclusion," the Vetements creative director added.

Gvasalia told the outlet that it also sent "a message" to those who feel like they don't belong: "You can achieve everything you want without becoming like everyone else!"

Smith told Harper's Bazaar that the ensemble was an ode to "all the pop rebels."

"This casual Karbie-core look was inspired by the play on proportions the brilliant Guram has created for the new Vetements collection. What better way to walk a hot-pink carpet?" they added.

Smith's ensemble may have also been a reference to the inclusivity in the movie.

Simu Liu, who is set to star in the film alongside Margot Robbie and Ryan Gosling, told Vanity Fair in December that director Greta Gerwig prioritized casting people with diverse shapes, sizes, and abilities in the movie's dance sequences.

"We were able to cast people of different shapes, sizes, differently abled, to all participate in this dance — all under this message of: You don't have to be blonde, white, or X, Y, Z in order to embody what it means to be a Barbie or a Ken," Liu said.

"I will say, going on set I was never isolated. I felt like I was going to work every day with a cast that really celebrated each other and celebrated each other's differences, no matter where we came from," he added.

Mattel has previously faced criticism for promoting an unrealistic body type with some of its Barbie figures, though in recent years the company has made efforts to create more inclusive models.

(Smith, Vetements, and Gvasalia did not immediately respond to Insider's request for comment regarding the inspiration behind Smith's outfit.)

Smith's ensemble is a departure from the outfits the 'Barbie' cast has worn to promote the movie

Robbie has channeled her character in a number of all-pink ensembles, including a baby-pink ball gown by Vivienne Westwood inspired by the 1960 "Enchanted Evening" Barbie doll at the London premiere on Wednesday, as InStyle reported.

Gosling, who plays Ken, wore a pastel-green suit to the premiere.

The "Barbie" cast also held a photo call at the London Eye in the city's capital to promote the film on the same evening as the premiere. Robbie and America Ferrera both wore red ensembles; Robbie wore a strapless minidress, and Ferrera opted for a long-sleeved gown with a heart-shaped cutout at the back.

Gerwig wore a floor-length, sparkling pink gown while Issa Rae opted for a halter-neck minidress with a green, pink, and red print and a feathery hem. Liu, meanwhile, chose an all-black outfit.
