In typical Marvel movie fashion, there’s a lot Emma Corrin can’t say about their role in the hotly anticipated Deadpool & Wolverine. “The secrecy [has been] taking years off my life,” Corrin, who uses they/them pronouns, tells Vanity Fair. The actor does admit to being “obsessed with” one particular cameo, “which I think is a performance of a lifetime by a certain individual,” teases Corrin. “I’m very excited for the world to see that.”

Until the film’s theatrical debut on July 26, Corrin has let their red-carpet styling do most of the talking. They say that Marvel offered “a certain license” toward going offbeat with their promotional tour looks, bringing high drama in Dilara Findikoglu for the film’s Rio de Janeiro bow and stunning in a belted black suit from Schiaparelli’s spring 2024 collection at the London premiere. That latter look “was probably more in the villainous vein and maybe linked to my character,” says Corrin of their character Cassandra Nova’s own belted corset.

At the world premiere of Deadpool & Wolverine, held in New York City on Monday, July 22, Corrin made a statement with not one, but two looks—shepherded by stylist Harry Lambert. “We knew that we wanted the moment in New York to hark back to old Hollywood glamour,” says Corrin. “The two outfits really contrast each other, which is fun.”

Walking the red carpet, Corrin opted for a strapless, high-cut, bejeweled Nina Ricci bodysuit by Harris Reed, which was accessorized with sheer black Calzedonia tights and pumps. “We wanted a Katharine Hepburn–type waist silhouette situation,” explains the actor, “but then to bring it into the modern era by making it this body suit.” Corrin was also intrigued by the custom ensemble’s tweed fabric paired with a furry off-the-shoulder wrap. “It’s a bit odd, but it’s frayed and nonchalant and anti-glamour in a way,” Corrin says of the fabric.

Ahead of the after-party, Corrin slipped into custom Miu Miu, sporting a metallic two-toned mini dress inspired by a fall 2004 runway look. “We wanted to honor the historical element of it,” says Corrin of shortening the archival piece’s silhouette, “but make it a bit edgier and more ‘me.’”

For both looks, Corrin worked with hairstylist Daniel Martin, makeup artist Gina Kane, and manicurist Dawn Sterling on a streamlined beauty aesthetic. Their slicked-back pixie cut was inspired by the likes of Buster Keaton and Linda Evangelista, while the black-and-burgundy makeup put a grunge spin on Hollywood influences—both classic like Lauren Bacall and Marlene Dietrich, and more modern, like ’90s supermodel Stella Tennant. Corrin, an ambassador for Cartier, adorned each ensemble with 18K white gold jewels from the brand.

Corrin has also been a longstanding ambassador of Miu Miu and finds “a lot of freedom” in the partnership, which began in 2020. “I’ve been working with them for such a long time now, it really feels like a family,” they say. They’re so supportive and give me a lot of space to be able to feel comfortable and empowered in what I’m wearing.”

Since breaking out as Princess Diana in Netflix’s The Crown, Corrin has continued to evolve their red-carpet style across films like My Policeman and shows including last year’s A Murder at the End of the World. “I think for me it’s always about feeling comfortable, but also a bit experimental,” says Corrin. “The red carpet is a space where I feel really free to be fluid in what I wear—play with the feminine and the masculine and the lines between both. It’s funny what elements of both of those things you can find combined in one outfit.”
