The brand last month posted a 28.8 percent hike in 2012 revenue on a comparable basis, with expanding operating margins.

Growth was seen from all of the brand's regions but especially in emerging markets like Japan, where revenue rose 46.7 percent.

"WALK LIKE A MODEL"

Also on Monday, British designer Stella McCartney opted for exaggerated volume, presenting contrasting pinstripes, voluminous coats and elongated skirts.

Interrupted by jolts of amethyst on a boucle coat and a body-covering silk dress, the mostly grey-and-black collection imparted a structured, masculine feel in line with McCartney's tomboy sensibility.

The Stella McCartney brand showed a "sharp increase in profitability" in 2012, according to part-owner PPR, which does not break out its results.

A key priority for the brand this year is expanding its store base in Asia, which already includes outlets in Japan, Thailand, South Korea and Singapore.

Underscoring the stature of the young British designer, U2's Bono, wearing his signature sunglasses, attracted a throng of photographers, as did American actress Jessica Alba, who gushed over the opulent Opera Garnier setting.

The show was delayed for 30 minutes by the tardy arrival of Paul McCartney, the designer's father.

"Walk, walk, walk like a model," the former Beatle was overheard saying to his wife Nancy Shevell as they walked down the runway to take their seats.

After the show, he called his daughter "the best".

"I thought it was beautiful. Very strong, very clean," he told reporter.
