MILAN, Apr 28 (Reuters) - Leading global menswear brand Gruppo Ermenegildo Zegna store sales rose more than 20 percent in the first three months of 2010, driven by growth in China and a recovery in the luxury market, it said on Wednesday.
Italian brand Zegna, best known for its tailored suits, also gave details on 2009 including a net profit fall of 73 percent to 17.3 million euros ($23.04 million) on restructuring costs and weak margins. It confirmed sales at 797 million euros, down 8.4 percent.
"The results achieved in a dramatic economic period ... give us more strength amid the recovery, of which we start to see positive signs, first from the American market," Chief Executive Ermenegildo Zegna said in a statement.
Zegna gave no further details on first-quarter sales.

Zegna, which celebrates its 100th birthday this year, said it would return to investing in Europe, with store openings in Monaco, Vienna, Amsterdam and Athens.
