Shopbop.com's Earth Friendly Category
I’m not sure how long this has been around, but the fabulous shopping site, Shopbop has a whole category (alongside Top Sellers and What’s Hot) called Earth Friendly, featuring clothes, shoes and accessories that are made of organic cotton, bamboo, and other sustainable fabrics.
Needing a new flowey summer piece to top off my shorts (but that is still appropriate for going out in the city), I found some really great options.
