I'm on the hunt for my first B-bag. I want a city and I've waitlisted for the violet, but just in case I don't want a purple bag (I'm a little afraid of colored bags), I'm leaning towards mastic. Do you think it will get dirty, and worn out easily? I saw plomb, it didn't do much for me, and I'm not on the market for another dark brown bag. There are not too many choices in the new collection, so maybe I picked the wrong time to get obssessed about B-bags.
