But this is no ordinary advert.
The Superman actress stars in the high street brand’s first ever 360 degree interactive digital campaign. Which means that the short film features a musical performance by the actress, who is wearing a custom-made beaded gown and shoes that she designed alongside the Topshop team, both of which will be available to buy on a special ‘made to order’ basis. The make-up used in the film will also be available to buy on topshop.com.
The glamorous film was produced by Bosworth’s fiancé, film director Michael Polish, and is inspired by the famous Michelle Pfeiffer piano scene from 1980s film The Fabulous Baker Boys. The song performed, Winter Wonderland, will be available to buy from iTunes alongside a selection of Bosworth’s past movies.
‘I think Kate looks effortlessly cool in the film,’ says Topshop’s creative director, Kate Phelan – and it's hard to disagree.
But what do you think? Watch it now and decide if you’ll be buying the dress, song or make-up...
