RISING SON: Stefano Pilati is still feeling cinematic. To present his spring/summer men’s wear collection for Yves Saint Laurent in Paris Wednesday night, he plans to screen a short film by Samuel Benchetrit, a French film director, actor – and the dashing other half of actress Anna Mouglalis. The house is mum on the plot, but the protagonist is Benchetrit’s 11-year-old son, Jules (and the fashion news will not be the launch of a children’s wear line.) Pilati also plans to stage a mini fashion show after the screening at YSL’s Rue d’Artois showrooms. Last season, Pilati featured a film by photographers Inez van Lamsweerde and Vinoodh Matadin that featured actor Michael Pitt.
