The Harry Potter star has revealed that she is now working with Alberta Ferretti on an organic fashion line.

"We are doing an organic clothing range," Watson told Us magazine. "I can't reveal the name yet but there will be more information about it soon."

Apparently the designer contacted Watson after learning of her involvement with People Tree. "She wrote to me and said, 'I saw what you did with People Tree and I think it's a great idea and will you do something with me?'" she added. "I will put it out there that I will work for anyone for free if they are prepared to make their clothing fair trade organic."

As for the line itself, Watson turned to '60s icon Jane Birkin for inspiration. "[The collection] is very classic, '60s Jane Birkin." The untitled line is due to launch before the last Harry Potter film is released, just after Christmas. Stay tuned...
