Founded to promote "lifestyles of health and sustainability" (or LOHAS), Gaiam is not only a shopping site, but also a vast resource of information related to green living, sustainable agriculture and mind/body wellness. The shopping section of the site is all-encompassing, offering everything from unbleached toilet paper to organic cotton bedsheets and yoga videos. And while much of the merchandise has a distinct hippie-chic or New Age vibe, there are also more urbane offerings, including this tank top, perfect with black pants for an evening at a restaurant.
