26-year-old Bonas, who dated Prince Harry for two years until April 2014, stars in the first of Mulberry's five Digital Stories. The adverts will feature emerging talent from the worlds of fashion and style, film and theatre, art and design, digital and new technology - and Cressida was a natural fit for the fun and carefree Spring/Summer 2015 campaign.
Photographer Michael Howells captured Cressida posing in a "modern interpretation of a garden" created inside an 18th century courthouse in London's Clerkenwell.
As for the covetable new season Mulberry bags? Cressida showcases the new reversible Delphie, the Cara Delevingne Bag, the Lily and Mini Lily as well as the Magnolia Dress, Blossom Dress and Peony Coat. (You can shop them all here.)
Although Cressida is busy focusing on her film career - she stars alongside Dame Judi Dench and Christoph Waltz in the upcoming film Tulip Fever - the actress has revealed why she couldn't say no when Mulberry came knocking at her door.
"It was great to be approached for the project and develop ideas with Mulberry," she said. "I loved the story and the attitude they wanted to convey. Our team wanted the girl in the film to have energy and fun, with the curiosity to explore which draws her up the stairs and into the mirrored room. And once she's there and feels that no one's watching – then she just wants to dance for the joy of it. The setting makes her feel free, and using dance to convey this feeling works so well for the story, and it adds signature Mulberry charm and wit."
