'Harry Potter' star Emma Watson has unveiled her third and final range for the ethical fashion label People Tree.

Watson, 20, who is pictured posing against a battered old motorcycle, while wearing a black mini-dress, paired with calf grazing pirate boots, opted for a music-festival vibe for her last spring/summer 2011 collection.

"I designed the collection last year after I'd started university in the US," the Telegraph quoted Watson as saying.

"Safia, People Tree's founder, and Misato, People Tree's designer, came out to work with me in Rhode Island. Together we decided on all the colours, fabrics, shapes and craft skills. Most of all, we took care to design a really wearable collection that truly celebrates the traditional skills of People Tree's fair trade groups around the world," she added. (ANI)
