Emma Watson unveiled her eco-friendly collection for Alberta Ferretti

Alberta Ferretti and Emma Watson have finally unveiled their eco-friendly fashion collaboration, Pure Threads. It features five Seventies-style pieces inspired by Miss Watson's fashion idol, actress Jane Birkin, and is made entirely from environmentally-friendly materials.

The Harry Potter star has designed for People Tree, modeled for Burberry and is current face of Lancome.

The capsule collection, called Pure Threads by Emma Watson Alberta Ferretti, went on sale today on the designer’s website.
Designs include a black lace embroidered cotton sleeveless dress, a white muslin long-sleeved lace shirt with ribbon and lace-trimmed denim shorts.

Miss Watson, 20, told how the designer approached her about the collaboration after learning of her involvement with People Tree.
She told MailOnline: ‘I have worn (Alberta Ferretti's) dresses at many red carpet events so I was absolutely thrilled when she contacted me for this eco-friendly project.
