Jessica Chastain shows just why she was named best-dressed... but even she walks to work in jeans

Having just landed the cover of Vanity Fair - in which she was named one of the best-dressed stars of the year - Jessica Chastain knows how to wear a designer dress with confidence.
And the flame-haired beauty did just that today as she emerged on the set of her latest movie in New York.
The 35-year-old actress stepped onto the set of The Disappearance of Eleanor Rigby in a tailored midnight blue dress pleated at the front.

The Help star paired her dress with black ballet flats, wore dark sunglasses and carried a large black leather tote.
Jessica came second on Vanity Fair's annual list, pipped to first place by the Duchess of Cambridge.
Despite her new status as a darling of the fashion scene, the in-demand actress was earlier spotted walking to work in her 'normal' clothes: ripped jeans, a crumpled black shirt and purple suede ankle boots.
The actress looked to be in deep concentration as she walked, more than likely going over script lines in her head.

The redhead shot to fame last year as the result of a handful of high-profile movies including The Help and Tree of Life, for which she garnered much critical praise.
She won over 35 critics' awards and was widely hailed as Hollywood's next big thing.
In the Vanity Fair article, on news stands this week, Jessica confesses to feelings of self-doubt and embarrassment.
'I've spent my life being embarrassed, the star told Vanity Fair. 'I don't want people to look at me.'

'I haven't been this unsure in a long time,' she confesses.
'I feel really, really terrified.'
Despite her recent success, mixed with the knowledge a career fall can be just around the corner at any time, the actress is not ready to cash in on big paydays just yet.
The magazine interview reveals that Jessica turned down a role in Iron Man 3 to shoot a project she's passionate about - The Disappearance of Eleanor Rigby.

Her new movie, in which she stars opposite Scottish actor James McAvoy, does not yet have a release date but is already attracting a lot of buzz because of its unusual format.
The story is about how a married couple in New York City deals with an emotional, life-altering experience, from two different perspectives.
It will be split into two feature films: 'His', giving the perspective of McAvoy's character, and 'Hers', offering the perspective of Chastain's character.
Jessica is also preparing for her Broadway debut in the title role of The Heiress, a 1947 play based on the Henry James novel Washington Square.
Paula Wagner, who is producing the play, says of Chastain: 'What's really rare here is to have an actress at the peak of her career say, "Stop, I'm going to do Broadway".
