Milan: Legendary Italian designer Giorgio Armani, the man who redefined modern elegance and gave the world the power suit, has died at the age of 91. The announcement was made by his company, which described him as “indefatigable to the end,” noting that he worked on new collections and future projects until his final days.

"With infinite sorrow, the Armani Group announces the passing of its creator, founder, and tireless driving force: Giorgio Armani," it said in a statement.

The best known contemporary designer, Armani opened his fashion house in Milan in 1975, quickly rising to the top of the industry and going on to dress the stars.

His funeral will be private, the group said, but well-wishers can pay respects beforehand at a funeral chamber open on Saturday and Sunday in Milan.

"Il Signor Armani, as he was always respectfully and admiringly called by employees and collaborators, passed away peacefully, surrounded by his loved ones," the company said.

"Indefatigable to the end, he worked until his final days, dedicating himself to the company, the collections, and the many ongoing and future projects," the company said.

Armani had cancelled his menswear show in Milan this year due to health reasons. He also missed the Paris Armani Prive show on doctors' orders.

"In 20 years of Armani Prive, it's the first time I'm not in Paris," he said in a statement sent to AFP in July.

"My doctors advised more rest, even though I felt ready."

He added that he had "followed and overseen every aspect of the show remotely", stressing: "I approved and signed off on everything you will see."

The Italian icon was credited with inventing red-carpet fashion, but also moved into a younger and less expensive range through Emporio Armani, and opened luxury hotels.
