For the fifth year in a row, Suzy Amis Cameron made sure the Oscars' red carpet contained a bit of green as well. 

Cameron's "Red Carpet Green Dress" competition, which challenges fashion designers to create Academy Award-worthy looks using sustainable and ethical materials, was represented last night by "Hercules" actor Kellan Lutz and "Quantum Solace" Bond girl Olga Kurylenko. 

While we had a general idea of what to visually expect from Lutz's tux a few weeks back (the materials can change, but a tux is always a tux), in typical fashion Amis Cameron waited until the red carpet last night to unveil Kurylenko's stunning red gown. 
“I really admire what Suzy does and it’s important to bring awareness to the fact that we need to be more green," Kurylenko said. "We don’t lose quality or beauty. It just takes a bit of thought. It just proved you don’t have to kill animals to wear beautiful things.”

According to sources, the 34-year-old actress' gown was made "from 100% GOTS certified organic peace silk and 100% GOTS certified organic silk. It was first hand-dyed with Sappanwood – a legume which produces a reddish-colored dye and is sustainable due to its fast growth rate – then overdyed with madder root to give it a deeper shade of red."

As for Lutz, his tuxedo jacket is "45% certified silk and 55% rPET; the pants are made of hemp and plant-dyedwith logwood; the waistcoat is made of hemp and 100-year-old

spitalfield silk and was dyed with marigold flowers."

Check out Lutz and Kurylenko being interviewed about their participation in the eco-friendly campaign below.
