HADASS KANTOROWICZ is on the fence. "I eat less meat than I used to," said Ms. Kantorowicz... "I'm definitely a lot more conscious than I used to be." While she appreciates the virtues of a meat-free diet, she stops short of embracing a vegan way of life, one that would ask her to forsake a croc-embossed bag or patent leather pumps. "And I'm not ready to wear hemp," she confided.

But a proliferation of vegan-friendly fashions and stores that ban animal products outright from their shelves may tempt her to change her tune. If she has yet to adopt the zero-tolerance approach advocated by the most militant vegetarians, she typifies the customer that many vegan marketers are now courting.

National chains like Whole Foods; boutiques like MooShoes, a New York outlet for imitation-leather wallets, belts and bags; online stores like Pangea; and eco-minded labels like Moral Fiber, Real Fake, Novacas (no cows) and Matt & Nat are encouraging shoppers, even those merely flirting with a "cruelty free" diet, to embrace its precepts not just in the kitchen but in their wardrobes. To their minds, vegan chic, once an oxymoron, is a glossy new marketing handle. Clothes and accessories once shunned for their aura of hair-shirt deprivation have acquired a hint of luxury.

Vegans, who may be thought of as extreme vegetarians, strive for a diet and way of life that is noninjurious to both animals and the environment, directly or through the processing of materials like leather, wool or silk. From motives of conscience or health, most reject shoes and clothing made from hides, even those made with animal-based glues and dyes.

"People are more conscious today of what they're wearing, why they're wearing it and how it affects the environment," said Robert Burke, a fashion retail consultant in New York. To ignore such issues "is not sexy today," he said. . . .
