In the new world of fashion marketing, it's all about flooding the zone. Brands such as Stella McCartney have understood that glossy magazine ads are no longer the most effective way of reaching their audience. Instead, they are using methods like street pamphleteering, Web sites and linkups with other firms to trumpet their presence. McCartney, who showed her spring-summer ready-to-wear collection in Paris on Thursday, has inked deals with Adidas for sportswear, LeSportsac for bags and Bendon for lingerie, as well as creating limited editions for high street retailers H&M and Target in Australia.

"Without visibility today, a luxury brand is not a luxury brand," said Cedric Charbit, general merchandise manager of women's fashion at the French department store chain Printemps.

"So I think it's pretty smart, and it speaks to Stella McCartney's audience, which rejects the current codes of the luxury sector because they are too ostentatious and too obvious," he added.

At Thursday's show, guests including her father, Paul McCartney, Lily Allen and Kanye West watched as models paraded in floaty floral dresses and featherweight paisley-patterned all-in-ones with a '70s feel.

Wearing loose hair and just a slick of lip balm, they emerged in front of a wall of green plants wearing billowing separates made from washed parachute silks in gentle tones of sky blue and dusty beige.

The British designer used techniques such as block-printing and quilting to give her outfits a hippie-luxe feel. But her training on Savile Row, the London hub of made-to-measure men's suits, was also evident in a cream single-breasted tuxedo suit.

Twiggy, the face of the Swinging Sixties, said McCartney was carrying on the tradition of cutting-edge British designers like Ossie Clark, Bill Gibb and Barbara Hulanicki, who designed the cult label Biba in the 1970s.

"Where she's brilliant is that there were lots of things that I probably wouldn't wear because it's not my age group, but then she throws in the jackets and the suits that everyone can wear," said Twiggy, 58.

"It's fun to see mad things that nobody can ever wear, but how wonderful to see a show that's exciting like that and women can wear them," she said.
