As an activist and entrepreneur, sustainability and being eco-friendly is very important to guest editor Josie Maran.

Josie and her company live by the mantra, 'luxury with a conscience,' which means they are dedicated to enhancing the natural beauty of its customers and the natural beauty of the earth. Josie Maran Cosmetics favors fair trade practices, sustainably harvested ingredients, and eco-friendly packaging.

In honor of Earth Day on April 22nd, Josie picked her favorite 'green' brands that are making a real difference. Not only are these brands sustainable, they also happen to be super chic. From former guest editor Jessica Alba's company Honest to ABC Kitchen and Home which strives to make eco-friendly (and stylish) products for your home, Josie's picks are officially on our must-shop list.
