Emma Watson is modelling for ethical fashion label People Tree for another season.

She may be one of the world's highest earning actresses and a student at Brown's University stateside, but Emma Watson is fast making a name for herself in the world of ethical fashion.

Fair Trade champions People Tree have just released pics of the Harry Potter star modelling the second collection of pieces that she has contributed to. Already in stores, the range features everything from pretty dresses and slouchy T-shirts to cool checked shirts and chunky knits, all made, of course, from Fair Trade fabrics.

Emma hasn't designed the collection but she has taken her role as collaborator very seriously. She even accompanied People Tree's founder, Safia Minney, on a trip to Bangladesh where she got to see the difference between factories in the slums and the Fair Trade factories where the label makes its clothes. 'Having seen the slums in Dhaka and the conditions in which these people live and work to produce 'fast fashion', I would say to those people that this is not the way we should be making clothes in the modern world,' she said. 'These workers have no rights and work every hour of the day just to feed their families. Fair Trade gives families the option to stay together, rather than one or both parents having to move to cities, and they are paid a fair wage. It empowers people and doesn't take away their dignity.'
