NEW YORK — Tony Lucia has bid auf wiedersehen to Hugo Boss USA. After a decade at the American arm of the Metzingen, Germany-based company — six years of which he spent as president and chief executive officer — Lucia resigned for personal reasons. Reached on Wednesday, he told WWD, “After 10 great years, I feel proud I can leave on top. It’s a great company, and I am leaving it in good hands. I have nothing but great things to say about everyone there.” A successor hasn’t been named, and in the interim, Andre Maeder of Hugo Boss’ board will manage the U.S. division. Lucia’s departure was first reported on dnrnews.com, the site of WWD’s sister publication DNR, on Tuesday. Lucia became president and ceo of Boss USA in 2002, succeeding Marty Staff. He joined Boss as senior vice president of sales in 1998. Prior to that, Lucia was vice president of sales for the men’s Le Collezioni collection at Giorgio Armani and earlier was vice president of men’s Collection sales at Donna Karan International. In the six years at the helm of Boss here, Lucia is said to have tripled the company’s total U.S. volume, which is estimated to be $345 million, with wholesale accounting for about 60 percent of business. Under Lucia, the company also tripled the number of directly operated stores — there are now 28 — and the company plans to open two more next month, in the Meatpacking District and in SoHo.
