In turn, many retail businesses, confronted by changing spending patterns, are becoming less brand-centric and more consumer-centric. And the logic of the runway shows -- now underway in New York and scheduled next month in Milan and Paris -- is being questioned by some of the top names in the business, who understand that shoppers don't want to wait six months between seeing designer clothes on the runway and being able to buy them in stores.
"It's the first time I can remember this kind of shift in the fashion paradigm," said David Wolfe, creative director of the Doneger Group, a New York trend forecasting firm. "The flashy addictive fashion [is] becoming less and less relevant to people's lives."
What's more relevant, it seems, are shopkeepers who keep the customer in mind and instant access to style and fashion advice provided by the Internet.
Not only does the Internet allow the convenience of shopping any time, anywhere, it's also a platform for a new generation of style arbiters who can dictate trends from their living rooms.
Aggregator websites let shoppers sift through styles and compare prices from dozens of online stores at once. Shopstyle, for example, offers cross-shopping by brand or search term at www.shopstyle .com and sends personalized e-mails with sale alerts. Covet ( www.covet.com) edits styles shown to individuals based on a questionnaire about preferences for color and silhouette. MyShape lets users input their measurements (www.myshape .com) and shop only for the items that fit their size and style profile.
And for those who can't be bothered to sit in front of a computer, mobile technology is making it possible to shop from the palm of your hand, which is why fashion designers are rushing to launch their own iPhone applications.
The result of all this interactivity is that there is more information than ever about fashion.
Runway looks, traditionally shown to buyers and the media six to eight months before they land in stores, can be seen online minutes after a designer shows them, worn by celebrities days later, and knocked off soon after that. Which means that sharp-shoulder silhouette that came down the Balmain runway in Paris in March was available at the mall long before the designer original arrived, and at a fraction of the price.
As trends seem to travel at warp speed, fashion magazines such as Vogue and Elle, which have traditionally been looked to for guidance on style, are struggling. The September issues, typically the biggest of the year, are nearly a third slimmer than last year's. Ad pages in Vogue decreased 36%, to 429.
Some of that money is moving to the Internet. Louis Vuitton North America more than doubled its digital ad spending in 2008, to $286,000, from $107,000 in 2007, according to TNS Media, a New York-based firm that monitors advertising spending in media.
And why not? The Internet makes it possible not only to read about fashion but to participate in it. The use of sites that enable users to create their own fashion spreads, share photos of themselves in different outfits and elicit wardrobe advice from their peers is skyrocketing.
"Between new technology and the economy, the fashion industry will never be the same," New York designer Norma Kamali said. "It makes you stand back and say, 'If I continue doing what I'm doing, I may not stay in business.' It's time to rethink and look at what's working and what's not."
One tradition that's being rethought is the semiannual New York runway show, which typically costs a designer $200,000 to $300,000 to mount. In July, the Council of Fashion Designers of America held a meeting in New York City where the relevance of fashion shows was discussed, along with their exclusivity (they are not open to the public).
It was a spirited debate that drew big names, including designers Diane von Furstenberg (who also serves as the council's president), Donna Karan, Betsey Johnson, Lazaro Hernandez and Jack McCollough of Proenza Schouler, and Vogue editor Anna Wintour.
"We spend so much money on shows, but what is it getting us?" Karan said at the meeting.
"Maybe there can be a fashion week that says 'trade' and another one that says 'shop.' " Von Furstenberg suggested.
Some designers are testing alternatives.
For the first time, on Thursday, Kamali will be showing clothes during New York Fashion Week that are available to purchase not six months from now, but on the spot.
