iamnotaplasticbag.jpg The Bag Lady first brought Anya Hindmarch's £5 I Am Not A Plastic Bag to our attention earlier this month, and it's such a good cause that we just had to blog about it on CatwalkQueen. That and because now Keira Knightley has jumped the waiting list and was snapped toting it around recently.

The Latest: Is Anya Hindmarch's "I'm Not A Plastic Bag" Really Eco-Friendly?

Launched recently at London Fashion Week, it's available in participating Sainsbury stores from April 25, at Anya's retail partners Dover Street Market in London, Colette in Paris and Villa Moda in Kuwait from mid March and on Anya's website.

No one involved in the project with What We Do will make any profit from the sale of the bag as they all believe in helping the environment. Every year, each person uses an average of 167 plastic bags, which obviously sit in landfills, doing nothing for the environment.

Do your part for the environment and get a cool Anya Hindmarch bag!
