The New York Times has reported that Hedi Slimane will be named on Wednesday as the new creative director at Yves Saint Laurent, according to a senior executive at YSL’s parent company, PPR, who has followed Mr. Slimane’s career in the world of artistic photography. The executive would not be named until after the announcement because of the sensitivity of the subject. The appointment has been expected since Stefano Pilati’s departure, after almost eight years as the label’s creative director, was announced last week. Mr. Slimane was the menswear director at YSL from 1996 to 2000.
