British designer Stella McCartney is the queen of earth friendly fashions, which is why I’m loving her new collection of eco-friendly sunglass collection, which launches this spring. Extensive research was done to ensure that raw materials used came from resources abundant in nature, including castor-oil seeds and citric acid. There are two acetate models and three metal models in varying color ways, such as nudes, greens, grays and berries. The collection is available at shopbop.com, stellamccartney.com and sunglasshut.com.
