The Oscars are an exercise in vanity, so why not double down with some Green vanity?

…at the Academy Awards, Missi Pyle, part of the ensemble cast of”The Artist,” will walk the red carpet in a flowing blue gown made from organic silk, hand-dyed with natural mineral pigments and lined with recycled polyester.

The gown was designed by Valentina Delfino, one of hundreds of designers around the world who submitted sketches to the third annual sustainable couture competition known as Red Carpet Green Dress in the hopes of presenting their creations on the most glamorous — and watched — red carpet in the world.

Pyle is the first actress in an Oscar-nominated film to wear the annual competition’s winning design. She was selected for her willowy, 5-foot-11-inch frame, her interest in sustainability — and all the attention surrounding “The Artist,” which is up for 10 awards.
