Eco-fashion aficionados gathered at Chateau Marmont on Thursday evening to celebrate Suzy Amis Cameron’s “Red Carpet Green Dress” campaign, which pairs emerging fashion designers with environmentally conscious mentors to create sustainable clothing for the Oscars red carpet.

This year’s designers are both fashion students at Paris’ ESMOD-ISEM, and won a contest to design a gown and a tuxedo that will be debuted on Oscar night. Manon Gabard is creating a gown for “Jane the Virgin” star Gina Rodriguez, and Tingting Chen is designing a tuxedo for “American Sniper’s” Jake McDorman.

McDorman’s tux will be made from eco-friendly fabrics including hemp silk and plant-dyed pea silk, and he told Variety that the fitting process has been piecemeal leading up to the big night: “It’s this patchwork of sustainable materials. It’s all coming together like a jigsaw — I don’t think I’ll see the final product until Sunday.”

The “American Sniper” thesp is impressed by Hollywood’s commitment to environmental initiatives. “Being in the entertainment industry has made me much more aware of those things. On a set you’ll find all the time that people are ordering vegan food for lunch and you’ve got to have gluten-free, vegan and vegetarian options at craft services,” he noted. “My girlfriend drives a Prius, and I feel like a monster now for not… It takes a little bit of educating yourself. I was living in New York for a long time and at least as far as transportation, I had a bike and I’d take the subway, so coming back here I’m questioning what changes I could make. I’ve always been the kind of guy who separates recycling and trash — that was the first thing I learned that I could manage myself, living on my own at 17, and I’ve kept up with that. It’s something that’s so important, if not the most important — how we take care of our planet.”

Suzy Amis Cameron — wife of director James Cameron — conceived the Red Carpet Green Dress contest during the press tour for her husband’s eco-minded blockbuster “Avatar,” in 2009, as a way to create fashion that is less damaging to the environment using organic, sustainable or recycled materials and more earth-friendly manufacturing techniques. The initiative raises funds for MUSE School CA, a non-profit, educational organization that Amis Cameron co-founded in 2006 with younger sister Rebecca Amis. The school aims to “empower children to realize their full potential through academic excellence, personal responsibility, compassionate relations, global consciousness and environmental awareness,” with 50% of students on financial aid. This year, Red Carpet Green Dress also partnered with sustainable fashion brand Reformation to create a capsule collection of six dresses called “No Red Carpet Needed,” with 25% of the profits benefiting MUSE.

“It always takes my breath away when I see what my baby sister and I created for these kids,” Amis Cameron said at the event. “My dream is to create a better world and a cleaner planet for our children to grow up on and to grow into and to raise their families into, and it’s Red Carpet Green Dress that has helped with that.”

Guests at the intimate soiree included Missi Pyle, Eric Olsen and Maggie Grace, with sponsorship provided by Audi and Lux & Eco.
