After announcing last week that a series of changes to revamp the sportswear brand were underway, Theory has released an impressive new ad with its redesigned logo – starring the elegant Russian supermodel Natalia Vodianova.

Vodianova – who recently announced a charity event in collaboration with Karlie Kloss, which is due to take place at London Fashion Week – is captured wearing the brand's minimalistic woollen pantsuits in all three colours of white, black and taupe. Candid close-up black and white shots of the 32-year-old mother of four, also feature in the new ads, which were shot by renowned photographer David Sims.
