I am going to purchase my first Louis (I'm so excited) and I'm trying to decide if I want the Damier Azur Pochette Bosphore with a Damier Azur Alexandra wallet or if I should go and get the new Damier Azur Berkeley bag. Any thoughts or suggestions? I love the Damier Azur line, but I don't know anything about how to clean it or if it gets really dirty...please help
