Kate Bosworth is Gorgeous... and Green!

Kate Bosworth joins former Melrose Place star Daphne Zuniga and American Idol‘s Elliott Yamin in hosting the Global Green USA’s Gorgeous & Green event in San Francisco on Tuesday night.

The 25-year-old actress was eco-fabulous in a black minidress embellished with swirls of zipper-edged ruffles down the front. Custom-made by designer Phillip Lim, the dress consists solely of green materials.

Supportive of Global Green’s mission to fight climate change and protect coastal cities, Kate shared, “The more I learn about how far we have come, the more I am inspired and grateful to be a part of [Global Green] to help find solutions and to inspire other people.”
