I've found an Eco Fashion World online! It's a useful guide and you can search by brand, store, category, eco criteria or country.
There's also a link on top of the site with 'deals'. On this page you can find a lot of coupon codes. For a Eco Fashion World dictionary, check 'glossary'.
Have fun in Eco Fashion World!
Love,
Renee-Louise
