She's no flapper: The roaring 20’s dominated Leicester Square on Wednesday evening as the glamorous cast of new period drama Live By Night attended its London premiere. But it was a rather more contemporary look that commanded attention courtesy of Stephanie Pratt

Showcasing a pair of nicely toned legs, Stephanie ensured she claimed her own share of the spotlight as she posed for photos ahead of the film’s first UK screening.

With an attention grabbing pattern and ruffled shoulders her choice of wardrobe proved to be a high point on a night dedicated to red carpet glamour.

The reality star – best known for her prominent roles on cancelled MTV show The Hills and Made in Chelsea – completed her look with a pair of simple stiletto heels, while her make-up was reduced to soft, subtle tones.

Stephanie was making an appearance at the event as brother Spencer makes a rather less glamorous return to Elstree and the Celebrity Big Bother house with wife Heidi Montag.  

Making her way across the red carpet she was joined by an array of Hollywood talent, including the forthcoming film's two stars - Sienna Miller and Ben Affleck.

The actress, 35, who plays Irish minx Emma Gould, absolutely oozed elegance in a figure-hugging monochrome dress as she joined her hunky co-star on the red carpet. 

Ben meanwhile looked typically dashing in a fitted three-piece navy suit with showed off his muscular frame.

Speaking to E!, Sienna recently admitted the pair were forced into a bevy of romantic scenes - some of which reduced her to fits of laughter.

'Ben and I are like brother and sister, thank God, so there was no awkwardness,' she said. 'There was just a lot of stupid giggling. He's very professional—I am not, but he is. 

'In that environment, it was a cool scene. There was a montage in the script saying we did it everywhere: in the car, in the bar...I was like: "That's an entire day of just love scenes! OK. How do we do this?"

'Obviously, by the time nine hours of it has gone past, I was shaking with tears running down my face. I mean, I can't tell you—but you have to laugh. Ben is just professional. It is what it is.' 

Live By Night is released across the United Kingdom and United States on January 13.
