Eco-Celeb: Sienna Miller

So what's a beautiful young actress and model to do after snagging Jude Law? Promote sustainable, fair-trade clothing, of course. Sienna Miller spoke up for People Tree, insisting, "There's no reason why organic and fair-trade clothing can't be sexy." We think she could probably make a paper bag look sexy, but we love that she loves the company's organically-farmed cotton and handwoven fabric anyway. ::You Magazine via People Tree [by KK]
