For the first time in its history, Tod's has tapped a celebrity to appear in one of its ad campaigns — and not just any celebrity, but actress and tabloid regular Sienna Miller, who flew into New York last month for a weekend photo shoot at Megu in TriBeCa, straight from the set of "The Edge of Love," co-starring Keira Knightley. Mikael Jansson shot Miller with the fall 2008 collection, overseen by Derek Lam, Tod's creative director (and recent CFDA accessories designer of the year). This season will mark Lam's first time designing the brand's accessories as well as its ready-to-wear. Miller spent her downtime during the shoot chatting with Lam and Diego Della Valle, president of Tod's. The ads will be seen worldwide in fashion and lifestyle magazines beginning in August.
