Olivia Wilde’s Met Gala 2026 Look Has a Cage on the Back

Olivia Wilde showed up to the 2026 Met Gala and made absolutely sure no one forgot she was there. The Booksmart director and actress walked the carpet at the Metropolitan Museum of Art on Monday night in a Thom Browne gown that was all sleek sophistication in the front — and a full-on fashion statement in the back, complete with a structural cage attached to a sweeping white tulle train.

Styled by Karla Welch, the 42-year-old wore the off-the-shoulder black gown without a single piece of jewelry, letting the architectural drama of the dress do all the talking. Her blond hair fell in loose beach waves, keeping the whole look effortlessly cool despite the gown’s undeniable theatrics.

A Look Built for the Theme

The cage-back design was a deliberate nod to this year’s Costume Institute theme, “Costume Art,” which explores the centrality of the dressed body through depictions and interpretations of the human form across the Met’s vast collection — pairing garments with artworks to reveal the relationship between clothing and the body. The dress code, “Fashion Is Art,” gave celebrities plenty of room to get creative, and Wilde leaned all the way in.

She’s hardly the only one making Thom Browne a red carpet moment lately. Cara Delevingne wore a design with painted-on abs to the Vanity Fair Oscar Party, and Teyana Taylor turned heads in a trompe-l’oeil style at the SAG Awards. But Wilde’s caged train might be the most literal interpretation of fashion-as-sculpture the designer has sent down a carpet in recent memory.

Fans on X weren’t shy about their feelings. “Olivia Wilde is so breathtaking! Not a stitch out of place. Of course Thom Browne fits like a glove,” one user wrote. Another put it more simply: “Yess Olivia Wilde surprising all of us with a dress that gives fashion in the front and PARTY in the back.”

Back at the Gala — and in the Conversation

This is Wilde’s first Met appearance since 2023, when she turned up to the Karl Lagerfeld-themed evening in a Chloé dress — only to find herself in the same gown as Vogue China Editor-in-Chief Margaret Zhang. This year, there’s no risk of that particular awkwardness. The cage sees to that.

Her Met Gala debut came nearly two decades ago, back in 2007 at the “Poiret: King of Fashion” celebration, when she wore a black halter dress. The boldness has only scaled up since.

Wilde also gave fans a peek behind the curtain before the big night. In a series of Instagram Stories, she posted a photo of herself on the subway in a baseball cap, gray hoodie, and blue coat, writing: “Mentally preparing for the Met by practicing not ever sitting down or having to pee.” In another Story, she showed off her freshly manicured nude nails with the caption, “Really have to stop taking such bold risks with my nail color.” Classic.

Adding a layer of tabloid intrigue to the evening: Wilde arrived on the carpet not long after Zoë Kravitz, who is currently engaged to Wilde’s ex Harry Styles. Whether the two crossed paths inside the museum is, for now, anyone’s guess.

Co-chairs for this year’s gala include Beyoncé, Nicole Kidman, Venus Williams, and Anna Wintour. But on the carpet Monday night, it was the woman in the cage-back gown who had people talking.
