SAN FRANCISCO - In a workshop in the city's Mission District, Ally Beran's team of fashion designers is sprawled out over buttons and spools of thread, hoping to stem global warming by stitching new outfits from thrift-store finds.
A brown lace applique from a scrap bin could make last year's castoff cashmere pop, Beran muses.
Or, she reckons, swatches from a tattered leather jacket could double as chic epaulettes on a high-end used sweater.
Designers of sustainable fashion are not only dominating New York catwalks and urban boutique racks this winter, many also are providing farmers with new markets for their crops.
As with the movement for locally harvested food, ecofashion's devotees seek to lower their toll on the earth by buying clothes made of recycled materials and sustainably harvested, homegrown fibers.
This year, American Apparel and yoga-gear retailer prAna will start selling shirts spun with cotton grown in California's Central Valley and sewn just a few hours away, in Southern California, to avoid burning fossil fuels in transporting the materials.
Beran's creations, marketed under the label William Good - an anagram of the company's business partner, thrift store giant Goodwill Industries - are sold only online and in stores near San Francisco, also to reduce their carbon footprint.
Farmers in the United States grow a small portion of the organic cotton used by the apparel industry, which still sources most of its fibers overseas in countries like Turkey, where labor and production costs are cheaper.
The market is clearly booming, however:
The nonprofit Organic Exchange predicts that sales of organic cotton fiber will reach $226 million by 2009, up from about $19 million in 2004.
As more companies seek to build a greener supply chain, American farmers are hoping that will translate into more demand for domestic crops.
Coral Rose, who spearheaded Wal-Mart's first purchase of organic yoga clothes in 2004 when she was a women's apparel buyer at Sams Club, said once companies start switching to natural fibers, it's only a matter of time before they start thinking about other sustainable-design practices.
Wal-Mart is now the biggest seller of organic cotton products worldwide.
"It's a total mindset shift at the design level," said Rose, now a consultant based in Fayetteville, Ark. "It holds the designer accountable for their designs and their impacts."
William Good CEO Nick Graham, a veteran designer who founded Joe Boxer in the 1980s, said the idea for his new company came to him as he wandered around a Goodwill store, thinking about all the used clothing that ends up in landfills.
"I thought we could do an organic line, but then I thought that's just more stuff we'd be creating," Graham said. "It's the American way to say we need more growth, but what if we created an economy with everything we've already used once?"
Still, analysts caution that until earth-friendly clothes come down in price, only a small group of consumers will think about their carbon footprint before they reach for their wallets.
"We've gotten more people aware or interested in ecological fashion, but most of the world's still looking for cheaper, better, faster," said Marshal Cohen, a fashion industry analyst at the NPD Group. "The message will resonate, but it's going to take more time."
