CLOTHES CALL: As Bruce Weber sees it, if a guy wants to avoid nudity, he can always wear a suit. Those are among the musings of the photographer in a short film he made for Stefano Pilati. It will be screened before Pilati’s Yves Saint Laurent men’s wear show in Paris on Friday and continues the designer’s tradition of mixing fashion and film. Titled “Ain’t Nothing Like the Real Thing,” the seven-minute film features a band of models, including up-and-coming face Paolo Anchisi, exclusive to YSL. A trailer with behind-the-scenes views of the Weber film is slated to make its debut on Facebook and YouTube when the show starts. Video of the fashion show, and Weber’s film, will go on those sites, plus ysl.com, a few hours later.
