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.
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.
