Sienna, who stars opposite Bradley Cooper in the movie, looked incredibly chic in the navy ensemble, which boasted a flat fold over front which was fastened with a gold buckle. 

She kept out the New York chill with a skin-tight, long sleeved leather top underneath the sleeveless jumpsuit - while the two garments perfectly matched in colour. 

The Layer Cake actress paired the look with black leather Mary Jane shoes, which tied in with her round-lens sunglasses.

Dare to go minimalist chic like Sienna in a modern jumpsuit

Sienna stepped out in New York City in a bold and modern Céline wool crepe jumpsuit that she styled with a long sleeve leather shirt.

The ensemble was finished off with Ray Ban round sunglasses and leather strap peep toe heels.

While en route to promote her new film Burnt at Good Morning America, she caught everyone's eye with her monochromatic look and her interesting mix of textures.

The round Ray-Ban sunglasses gave a nod to the 60's that is very refreshing when paired with such a futuristic look. Her black lizard peep toe shoes bring a softness to this striking silhouette.

Sienna kept her make-up minimal with a dab of pink lip gloss and a fashionable strong brow leading the look - otherwise she allowed her alabaster complexion to shine through.

The mother-of-one wore her trademark blonde locks in a chic centre-parting while the rest was pinned into an elegant chignon.

Showing the intricate attention to details with her look, Sienna had lacquered her nails in the same hue as her outfit.

Sienna has been extremely busy of late as just a night before her GMA appearance, she and Bradley were setting off to promote the movie yet again.

The two stars, who also appeared in American Sniper together, were both in attendance at a SAG Foundation Conversations Screening and Q&A for the new flick.  

Sienna looked chic as ever as she wore a long black patterned dress which featured a very low-cut neckline for the event held at The New School.

The extreme cleavage looked more ethereal and understated on the naturally stylish star, though.

Her medium-length blonde locks were worn down flowing over her shoulders as she sported natural, complementary make-up on her face.

Bradley, 40, was dapper in a brown blazer over a checked grey button-down and black jeans, arriving alongside his second-time movie colleague.

The two were also joined by co-stars Daniel Bruhl and Sam Keeley as they chatted about the highly-anticipated film.

The new film features a distinctly different tone to 2014's American Sniper; all about heroic Navy S.E.A.L. sniper Chris Kyle (played by Cooper) and the wife he left behind Taya (played by Miller).

This time around, the acting pair take on a comedy, which they began to film in 2014, amidst the hype of their true life portrayal.

Sienna plays the Helene to Bradley's Adam Jones; a top chef who ditches his drugs and an associated bad reputation to return to London in the hopes of heading up a Michelin-star restaurant.

It's another big part for Sienna, who's thought to have recently split with the father of her only child Marlowe.

Her latest project spurred her on to discuss the hot topic of sexism in the acting industry during a chat beside Bradley on Wednesday.

Sienna revealed that she had recently been forced to turn down a role because of the vast gap in pay between herself and a male colleague.

She told E! News: 'I walked away from a play I wanted to do because I was offered less than half of what the other man was offered and it was just the two of us.'

It was recently revealed that Bradley's American Hustle co-star Jennifer Lawrence, along with Amy Adams, were paid much less than their male counterparts, with Jennifer insisting that she had failed as a negotiator. 

Bradley supported Sienna by adding: 'One thing I could say is that's interesting because if you think that you only deserve a certain amount and that's not correct.  

'It's about changing that mindset and sticking up for yourself the way that Sienna did.' 

Burnt is set for release in the US this Friday, October 23 followed by a UK release on November 6.
