Olivia Wilde is known as much for her film roles as for her dedication to political and environmental causes.
As well as supporting the Fair Foods campaign, Olivia is a committed vegan and is a board member of Artists for Peace and Justice.
So it was a natural choice for H&M to cast the 30-year-old as the face of its new Conscious Exclusive campaign. As well as the fact that she doesn't look half bad in the clothes.
Speaking about becoming the face of the collection, Olivia Wilde said: 'Sustainability is one of my biggest passions. I'm proud to be the face of H&M Conscious Exclusive, a collection which shows the stylishness of sustainability.'
The new collection in H&M's continued focus on sustainable fashion is heavy on the dresses. which come in luxe organic fabrics, including silk, cotton, linen and leather, proving that sustainable clothes don't have to be limiting or boring.
I love the look of this year's collection, said H&M's Head of Design for New Development, Ann-Sofie Johansson. 'The pieces are full of character in the most beautiful prints, all made from sustainable materials.
The collection will be available in around 200 stores worldwide, and online, from 16th April 2015.
