Maisie Williams ditched her Arya Stark persona in "Game of Thrones" as she was a picture of style in a cut-out dress during the Annual Comic-Con Party held at FLOAT at The Hard Rock Hotel hosted by Entertainment Weekly on Saturday.

"Maisie looked all grown-up in her retro number, which featured cut-outs at the waist and crystal-embellished embroidery on the bodice," Daily Mail reported. "The British beauty made a big impact on the red carpet in the ethereal outfit, which was set off with a pair of strappy nude stilettos."

Apart from a role in the popular British TV show, "Dr. Who," Maisie Williams will also be seen in "The Falling" where she plays a schoolgirl circa 1969 who will struggle with the death of her friend as well as her raging hormones.

In an interview with TIME magazine, Maisie Williams revealed that she's had fun playing Arya Stark in "Game of Thrones" season 6 but the sex scenes in "The Falling" were more difficult to shoot.

"I feel like nude or sex scenes are more awkward-for anyone. That kind of tops it for the most weird days on set that I've had," she said. "And [her partner in the scene, Joe Cole] has had a little more experience with that, and I'd never done a scene like this. It was quite a big deal because I was 16 when we shot it."

"It was also the first film I shot on my own, without my mum. But it was a necessary scene. And now I've done it and it's never going to be as scary again."

Maisie Williams also weighed in how women are treated in "Game of Thrones" season 5 as she claimed that the show tried to make a realistic portrayal.

"I feel like people are treated badly on it all the time-men, women, girls, boys...animals. It's set in a time where women didn't have it easy. Women haven't had it good over history, like it's been a pretty s*** time for us. And like a lot of other fantasy, the show takes on controversial topics," Arya Stark said.
