I'd never really followed Jessica Chastain's style but that all changed recently. At the ELLE Style Awards earlier this month she wowed the crowd in a black Alexander McQueen dress and last week she managed to pull off one of the brand's tricky two piece skirt suits at an event in New York.

But it doesn't end there. The actress struck gold again in this green sleeveless chiffon gown with sheer lace detailing from the S/S12 Elie Saab collection to attend the 40th anniversary of Charlie Chaplin's honorary Academic Award.

Are you as impressed with the look as we are?

Last night ELLE hosted their 15th annual ELLE Style Awards. The event, which took place in London's Savoy Hotel, saw Alexa Chung brought back to serve as host and guests were treated to a performance over dinner by Critics Choice Award winner, Emeli Sandé who was joined on the stage Professor Green in the after-party.

Red carpet looks were strong, particularly from Tali Lennox in Julien Macdonald, Jessica Chastain in Alexander McQueen, Chung in Stella McCartney and Rosie Huntington-Whiteley in Antonio Berardi.

But outfits aside, the one thing you can always count on at the event is a good speech or two and last night was no different. Last year everyone was talking about Vivienne Westwood's 'interesting' confession that she didn't know who Emma Watson but this year was even more memorable. Johnny Johannsson, Acne's creative director, had us all impressed as he sang a Swedish celebratory song to pick up the award for Best Contemporary Brand but it was Cuba Goodings Jr who stole the show. Before presenting the Style Icon award to Huntington-Whiteley, he had the crowd taking shots of their drinks after saying that, "this is the first party I've been to where I feel I need to loose weight."

Elle are a luck bunch aren't they? Last year they bagged Henry Holland to co-host their annual Style Awards and today the magazine announced that they've secured Alexa Chung again to join editor Lorraine Candy to host the event on Monday.

We couldn't think of a better candidate. After all, Chung does epitomise the ELLE girl. "It’s exciting to have Alexa back to present the ELLE Style Awards for the third time," Lorraine Candy explained. "She’s such a true ELLE girl, the woman everyone wants to be, and ever since we were the first fashion magazine to put her on the cover, in October 2008, we’ve enjoyed working with her – with two bestselling covers as a result. Her innate sense of style is an inspiration to our readers and young women internationally, which makes her the perfect choice to introduce the winners at the year’s most stylish awards ceremony."

Chung revealed that she's pleased to be back hosting the annual event. "It's an honour to have been asked once again to host the Elle Style Awards," she said. "It's a daunting prospect but will I'm sure be an incredibly fun way to celebrate Valentines day”

ELLE UK is on a roll. The last few months have seen the magazine bag a number of accolades. In June the magazine was awarded their first D&AD award in the Magazine and Newspaper Design category for their 'London Issue' fronted by Lily Allen and last month they reached a colossal 100,000 twitter followers, a reported 50,000 more than their competitors.

And it doesn't stop there. Today the magazine announced that designer and model Ben Grimes has come on board as the magazine's Contributing Editor. The role will see Grimes report on all the biggest events and launches happening in the industry.

"This is the first time we have had a contributing editor at ELLE who will work outside of the editorial content. Ben will be representing the magazine at a variety of events," editor-in-chief Lorraine Candy said. Although we're all thrilled by the news many were left wondering how Candy decided to appoint Grimes as opposed to the more obvious Alexa Chung but she was quick to explain why Grimes was the perfect candidate.

"Her knowledge of fashion, art, music and her spirited sense of humour made her the perfect choice to be ELLE's filter on everything new that is happening now," she said. "ELLE is the only monthly glossy that is predictive rather than reactive - it's our job to bring readers news on cultural and fashion trends before they happen, which is why we need people in the know to relay that information to us. Ben will be able to do that. She is already working on our Shop Girl to Stylist initiative and interviewed celebrities on the red carpet for us at the ELLE Style Awards. She will be our reader’s eyes and ears at events during London Fashion Week and available as a commentator for us as part of our in-depth coverage of British fashion."

Grimes seems thrilled at her new role saying today that "It's a new and exciting venture for me and as Elle is a favourite publication of mine, it’s also a big honour!"

In just a few weeks, "the fashion Oscars" are coming back to London. The 13th-annual ELLE Style Awards are scheduled for February 22, with editor-in-chief Lorraine Candy co-hosting with a friend of the magazine, Henry Holland. This is the first time Candy has led the festivities, but that seems only appropriate for ELLE's 25th year in print.

We're told that this year's awards (sponsored by Next) are going to be even more star-studded than normal, with a host of celebrity presenters lined up and "a special performance by one of ELLE’s favourite emerging British artists." We have our suspicions as to who that might be, but the real question is, who'll take home the big awards of the night? With previous honourees including Vivienne Westwood, Victoria Beckham, Freida Pinto and Christopher Kane, the bar has been set high for this year's crowd.
