SEXY FEET: Stuart Weitzman’s fall campaign portrays Natalia Vodianova in little more than her “Stuarts.” Shot by Mario Testino, the ads continue the theme, begun last spring, that feature Vodianova, with her tousled hair, wearing high heels and boots, with little else. The imagery plays on the fact that Stuart Weitzmans are the first thing you put on in the morning and the last thing you take off at night. Created by Lipman, the ads are intended to capture the sexiness of the brand in a chic way, showcasing the stiletto, boot and shoe styles. The campaign will launch in September in the U.S., Italy, France, Spain and Asia. In the U.S., the print buy includes Vogue, Elle, Harper’s Bazaar, W, Interview, Vanity Fair, V Magazine, the New York Times, Du Jour and InStyle. Outdoor ads (billboards and kiosks) will appear in Los Angeles, New York, Miami, Milan and Paris. Behind-the-scenes video will be featured on stuartweitzman.com and in Stuart Weitzman boutiques worldwide. According to the company, the budget is up 62 percent from last fall.
