Chanel Denim Coco Cabas Bag
A Chanel denim coco cabas I found from Purseblog.
There is one from Cameron Diaz.
Can you see the difference? Both are made of washed denim. But the authentic denim looks more natural because the contrast between the washed denim and dark denim is more obvious. As to the replica denim, the washed part is evenly spreaded all over the bag and the contrast is less visible than the authentic.
