It seems that Emma Watson really has a knack for this fashion design thing. Looking at her latest and last People Tree collaboration, you can totally see that Watson has pushed the sustainable fashion label in a more, if you will, wearable direction.

The actress along with Safia, People Tree’s founder, and Misato, People Tree’s designer, started working on the Spring 2011 line last year up in Rhode Island just after Watson, 20, stated classes at Brown University. Matter of fact, she's actually been pretty hands on with People Tree since she signed on as the face of the Fairtrade brand in September 2009. But that's because she believes in the principal and power behind sustainable fashion.

"Fashion is a great way to empower people and give them skills; rather than give cash to charity you can help people by buying the clothes they make and supporting things they take pride in," she recently told a fashion publication. " I think young people like me are becoming increasingly aware of the humanitarian issues surrounding fast fashion and want to make good choices but there aren't many options out there.

And we totally agree. Now what was harder to agree on was what our favorite piece of the collection, which features jersey harem parents, blazers, dresses, tees, and tank tops, would be.

Emma Watson goes for the sultry look in her final collaboration with People Tree

It looks like Emma Watson's final People Tree collection will be the best yet, with the brand releasing a sneak-peek for the Spring/Summer collection.

Posing next to a motorbike, Emma looks sexy and sultry as she wears the thigh-skimming Sasha Drape Dress, £48, and and brown boots.

The 20-year-old has been extremely hands-on with the designing of the clothes ever since she was signed on as the face of the Fairtrade label in September of 2009.
