     The January fashion show, called FutureFashion, exemplified how far green design has come.

Organized by the New York-based nonprofit Earth Pledge, the show inspired many top designers

to work with sustainable fabrics for the first time. Several have since made pledges to include organic

fabrics in their lines.

     The designers who undertake green fashion still face many challenges. Scott Hahn, cofounder with

Gregory of Rogan and Loomstate, which uses all-organic cotton, says high-quality sustainable materials

can still be tough to finD．"Most designers with existing labels are finding there aren't comparable fabrics

that can just replace what you're doing and what your customers are used to," he says. For example,

organic cotton and non-organic cotton are virtually indistinguishable once woven into a dress. But some

popular synthetics, like stretch nylon, still have few eco-friendly equivalents.

     Those who do make the switch are finding they have more support. Last year the influential trade

show Designers & Agents stopped charging its participation fee for young green entrepreneurs (企业

家) who attend its two springtime shows in Los Angeles and New York and gave special recognition to

designers whose collections are at least 25% sustainable. It now counts more than 50 green designers,

up from fewer than a dozen two years ago. This week Wal-Mart is set to announce a major initiative

aimed at helping cotton farmers go organic: it will buy transitional (过渡型的) cotton at higher prices,

thus helping to expand the supply of a key sustainable material. "Mainstream is about to occur," says

Hahn.

     Some analysts are less sure. Among consumers, only 18% are even aware that ecofashion exists,

up from 6% four years ago. Natalie Hormilla, a fashion writer, is an example of the unconverted

consumer. When asked if she owned any sustainable clothes, she replied: "Not that I'm aware of."

Like most consumers, she finds little time to shop, and when she does, she's on the hunt for "cute

stuff that isn't too expensive." By her own admission, green just isn't yet on her minD．But-thanks

to the combined efforts of designers, retailers and suppliers-one day it will be.
