Paul Deneve, chief executive officer at Lanvin, has sung his last hoo-rah at the uber-chic brand. A Lanvin spokeswoman in Paris confirmed his departure Wednesday, citing “diverging points of view” on the direction of the company, which is controlled by Taiwanese publishing magnate Shaw-Lan Wang. The spokeswoman declined further comment, and said an announcement about Deneve’s successor would be forthcoming. She did not give any time frame. Deneve is the second top manager to leave Lanvin recently. Last month, Stella McCartney said she tapped Frederick Lukoff, Lanvin’s director of business development, as her new president and chief executive officer, effective Feb. 23.
