Lauren Bush

You know those ubiquitous canvas FEED tote bags that everyone has been carrying around recently? You can thank Lauren Bush for that. The fashion model (and niece of George W. Bush) teamed up with the U.N. World Food Program to raise awareness about world hunger and to bring style to a substantive issue. In 2008, Bush also launched a sustainable clothing line made entirely of organic fabrics and cotton alternatives like bamboo and hemp silk.
