I have the cerulean colorblock willis and after having it for barely 2 weeks it got wear marks on the bottom front, the color faded slightly..
I will say this too, waxed leather is easier to get scratches on it. I placed my bag down on a shelf and when I picked it back up I noticed it had a small scratch on the back.
I figure it just adds more personality to the bag, the marks do not make the bag look any less attractive, but its discouraging when something like this occurs when your handbag is still new...
