PARIS — Thierry Andretta, managing director of Lanvin since 2009, has resigned from his position, WWD has learned.

A Lanvin spokeswoman confirmed his departure, citing “personal reasons.”

She added that Shaw-Lan Wang, Lanvin’s majority owner, chairman and chief executive officer, has asked Michèle Huiban, Lanvin’s chief operating officer, to “assume the operational management” of the firm.

Andretta arrived at Lanvin with the title executive vice president, and spearheaded a global retail expansion. To wit: Lanvin creative director Alber Elbaz is slated to travel to Hong Kong for the April 18 opening of a Lanvin flagship there.

He also introduced a range of luxury children’s wear, and made leather goods a strategic priority with a view to “make all accessories as recognizable as Elbaz’s inimitable fashions.”

Revenues at the fashion house nearly doubled during Andretta’s tenure, to an estimated 240 million euros, or $308.5 million at average exchange rates, in 2012.

According to sources, Andretta and Wang, a Taiwanese media magnate, recently had disagreements over strategy at the fast-growing company.

Andretta could not immediately be reached for comment.

Also during Andretta’s tenure, Wang completed her mission of finding a partner willing to help her take the fashion company to the next level, selling a 25 percent stake in Lanvin’s parent, Arpège SAS, to entrepreneur Ralph Bartel via a family trust.

Prior to Lanvin, Andretta was ceo at Moschino in Milan.

An Italian national, he had succeeded deputy general manager Paul Deneve, who had exited Lanvin in 2008, with the company citing “diverging points of view” on the direction of the fashion house. (Deneve is now ceo at Saint Laurent.)

Prior to Moschino, Andretta had worked in senior management positions at Replay, Belfe, Gucci Group, Céline and Emanuel Ungaro.

Andretta is also president of France’s Chambre Syndicale for Men’s Fashion.
