Gwyneth Paltrow

Iron Man

star Gwyneth Paltrow loves to sport clothes from her pal Stella McCartney. The designer, who was raised on an organic farm, has long created leather-free accessories, and recently developed a line of environmentally-friendly skincare. As McCartney asked Wish magazine, "Why shouldn't it be possible to adopt a more natural, organic lifestyle without forgoing luxury? I believe it's possible to have all these things without compromising your personal beliefs and the safety of the environment."

Hayden Panettiere

Green crusader Hayden Panettiere got ethically pretty in a bamboo dress from Juul. Of her famous fan, designer Suzanne Juul couldn't be prouder: "She walks her talk. For me that is what makes Hayden so special." Those wanting to shop green like the Heroes star should "find out what quality of fabric, knit, etc., is available," says Juul. "Some green products itch. Some are soft and gentle."

Liv Tyler

When Hulk star Liv Tyler bought a pair of TOMS shoes, she also gave a gift-the company donates a pair of shoes to a needy child with every pair purchased. "It is definitely time for all of us to think before we consume," says TOMS founder Blake Mycoskie. "You should not only consider what you buy, but whether you need to buy at all." In the case of TOMS shoes, there's no need to think twice!

Mena Suvari

When actress Mena Suvari debuted a design from Rogan for Target, she was showing off Rogan Gregory's fourth foray into green clothing. Gregory added the Go Collection line to his work with Edun (alongside Bono and Ali Hewson), Loomstate (with partner Scott Hahn) and his CFDA Award-winning self-named collection. And it's no wonder he took on the extra workload. Said the designer, "Target said they would make the whole collection of organic and sustainable fibers and I could design whatever I wanted, so I couldn't resist."
