Stella McCartney Eco-Collection

Stella McCartney

Who she is:

A designer as skillful with sporty pieces as with luxury ready-to-wear.

How she's green:
A strict vegetarian, she uses no fur or leather—ever. McCartney's clothes are all about respect for nature, whether it's saving animals or sustaining the planet.

Her collection:
McCartney's new eco-collection for Barneys New York either leaves fabrics natural or uses dyes that don't contaminate water supplies (far left, racerback top, $465; D-ring-belted jeans, $295). Her collaboration with Adidas forges ahead with, near left, a bamboo, polyester, and cotton tee ($100), organic cotton cropped pants ($120), and synthetic flats. ($100). A wheelie made of recycled nylon ($420), below left, is from her line of bags for LeSportsac.
John Patrick Eco-Collection

John Patrick

Who he is:

The designer of Organic, which he founded in 2004.

How he's green:
His production—from spinning and weaving to dyeing and sewing—is based mostly in Peru and uses organic materials. "I realized that I could make things I loved, not just racks of products that were disposable after one season."

His collection:
Neutral colors and fresh textures make Organic's casual-chic cotton pieces easy to mix. A chunky knit cardigan ($295), near right, slides over an embroidered tank ($225) and cotton pants ($165). Wide-legged, high-waisted linen trousers ($270), far right, prove that eco-style can be very on trend; a recycled pima cotton top ($270) is inspired by peasant blouses. Swatches of colors to "dye" for, below, have their roots in plant life.
Phillip Lim Eco-Collection

Phillip Lim

Who he is:

His 2-year-old company, 3.1 Phillip Lim, won last year's prestigious Swarovski Award for Emerging Talent.

How he's green:
His new collection for Barneys New York, Go Green Go, uses high-quality, undyed organic fabrics. Lim's easy, streamlined, totally unboring clothes bring a certain sleekness to the organic realm.

His collection:
Classic shapes with a touch of vintage are Lim's thing; here they put their most enlightened foot forward in pale, natural tones, great for spring weather. The modified biker jacket with an intriguing zip hem ($495), near right, looks perfectly proportioned over a slighter longer shell ($185) and full cropped pants ($225). A double-breasted car coat, far right, has cool wrist ties and a flattering neckline ($595).
Rogan Gregory Eco-Collection

Rogan Gregory

Who he is:

Cofounder of Rogan, Loomstate, and Edun.

How he's green:
He's a champion of environmentally responsible practices. Gregory's parents, ardent recyclers, were skeptical about his career as a designer, but now they see what fashion can do for the world.

From his collection:
Ethical denim is on the rise. "A small fashion company trying to make a big point" is how Ali Hewson describes Edun, whose spring line includes, left, a shapely silk hoodie ($255), organic cotton tee ($95), and beautifully cut jeans ($185). Loomstate makes sure that all stages of manufacturing for its jeans, above (white, $150; blue, $170), maintain the highest environmental and labor standards.
