Leave it to Stella McCartney to make eco-friendly fashions feel more Alice Waters than Healthy Choice — that is to say, they're more focused on sustainable and attractive products and systems than pure gimmick. For her latest project, she's teamed up with Luxottica to create eco-friendly sunglasses featuring bio-injected plastic made from 54% castor oil seeds, which require very little water and pesticides to grow. The materials are natural and renewable, and come in three "plastic" and two metal versions. Find them in stores this spring. (WWD)
