With its new “H&M for Water” collection, Swedish retailer H&M is rolling out a whole new line of Hawaiian-themed dresses, shirts, swimsuits, board shorts, and accessories that are made of sustainable materials like as organic cottonTencel, linen and silk. But green fabric isn’t the only thing we like about the resort wear; 25 percent of proceeds will benefit WaterAid, an international nonprofit that provides clean water and sanitation to some of the world’s poorest communities.
