The witch is back!

"Harry Potter" star Emma Watson is brewing up a new organic clothing line with designer Alberta Ferretti, Us Magazine reports.

"We are doing an organic clothing range," Watson told the magazine.

"I can't reveal the name yet but there will be more information about it soon."

And with the pixie-haired beauty citing her style inspiration as "very classic, '60s Jane Birkin," we may have a little trouble summoning up some patience.

The Burberry model also told Us that Ferretti approached her about collaborating on a line -- reportedly set to launch "just after Christmas -- after seeing her organic People Tree collection.

"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?'"

"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."

Aw. An earth girl after our own heart.
