Maisie Williams dons bold black leather ensemble as she leads stars at The New Look premiere in New York… after revealing she underwent punishing regime to lose 26lbs for latest role

Maisie Williams wore an all-black Christian Dior ensemble as she walked the red carpet at the premiere of The New Look at Florence Gould Hall in New York City on Monday night.

The 26-year-old actress was dressed in a black leather dress with an attached scarf over her shoulders and around her waist, and a midi-length A-line dress.

The Game of Thrones star accessorized with a matching leather beret, a single diamond earring, dark tights, sheer gloves and velvet pointed-toe heels.

The actress, who plays Catherine Dior in the series, was joined by her co-stars from the AppleTV+ series, including Juliette Binoche, Glenn Close, Ben Mendelsohn and John Malkovich, as well as actress Noomi Rapace and musician Jack Antonoff.

The actress stepped out in a show-stopping look at New York Fashion Week in New York City earlier Monday.

Williams looked ravishing in a unique long-sleeved tea dress with bubble buttons and a flowing, quilted texture.

Williams paired the stunning garment with a black crew cap and a forest green velvet handbag with yellow gold detailing.

Williams – who revealed how she quickly lost 26 pounds for her role as Catherine Dior in her new biopic The New Look – wore sheer black tights and patent leather ankle-strap pumps.

She turned up the drama with orange-tinted retro sunglasses and a deep oxblood lip.

The Doctor Who vet wore a pair of black velvet gloves with the backs of her hands visible.

She wore no jewelry other than a pair of dainty diamond earrings.

She wore a similar look to Apple TV’s TCA Winter Press Tour in Pasadena, California on February 5.

On Monday evening she will appear on The Tonight Show Starring Jimmy Fallon to talk about her new show The New Look.

In the biopic series, she will play Catherine Dior, Christian Dior’s sister.

The show tells the story of how Dior, Coco Chanel, Pierre Balmain and Cristóbal Balenciaga endured the horrors of World War II and launched modern fashion.

In 1941, Catherine Dior joined the resistance before she was later arrested by the Nazis and imprisoned in the Ravensbrück concentration camp.

For the role, Williams explained in a Harper’s Bazaar UK cover interview that she lost 26 pounds by going through a difficult regimen.

She said she was carefully monitored by medical professionals while drastically reducing her food intake.

The actress also explained that she lost most of her weight through sweating, in addition to eating very little.

“I had to get up at four in the morning to start sweating,” she said, explaining what a day of filming preparation was for her.

“The night before, around 7 or 8 p.m., I was allowed to eat something salty and dehydrating: some smoked salmon and a small glass of wine.

“Then I was given a boiling hot bath with lots of salts in it,” she continued. “And I kind of drifted off to bed and slept maybe three hours and woke up with a handful of nuts.”

However, because she ate so little, she said she had trouble winding down.

“I couldn’t sleep all night right now,” she added.
