Kristen Stewart caught everyone's attention at the BFI London Film Festival on October 7.
The actress was in attendance for the premiere of Spencer, her soon-to-be released biopic in which she portrays the late Princess Diana.
Scroll down to see the gorgeous designer gown the Twilight star wore to the event.
Stewart stepped out in a slate gray column dress by Chanel. The strapless frock featured different shades of embellishments, and she opted for dark gray heeled sandals.
Aside from a few rings, the star decided to ditch the jewelry and let the sparkly number do all the talking.
The actress' strawberry blonde tresses were styled in loose waves, and aside from some edgy dark gray eyeshadow, she went for a natural makeup look and wore a light shade of polish on her nails.
The drama comes out on November 5, but the California native is already receiving rave reviews and earning Oscar buzz!
The movie takes place just before Diana and Prince Charles split.
"The marriage of Princess Diana and Prince Charles (Jack Farthing) has long since grown cold. Though rumors of affairs and a divorce abound, peace is ordained for the Christmas festivities at the Queen’s Sandringham Estate," the official synopsis reads. "There’s eating and drinking, shooting and hunting. Diana knows the game. But this year, things will be profoundly different. Spencer is an imagining of what might have happened during those few fateful days."
The star revealed that playing the Princess of Wales was a once-in-a-lifetime role.
"I took more pleasure in my physicality making this movie than I have on anything," she shared. "I felt more free and alive and able to move — and taller, even."
When it comes to Diana's title of being a fashion icon, the Charlie's Angels star explained the mom-of-two "was someone who used clothes as armor but was so constantly available and visible. She couldn’t hide, she wore her heart on her sleeve and that, to me, is the coolest thing she did."
"I look at [Diana], the pictures and fleeting video clips, and I feel the ground shakes and you don’t know what’s going to happen. [She] sticks out like a sparkly house on fire," Stewart expressed. "The really sad thing about her is that as normal and casual and disarming in her air [as she is], immediately she also felt so isolated and lonely. She made everyone else feel accompanied and bolstered by this light and all she wanted was to have it back."
