Short answer: does it get dirty easily: yes.
I used 3 coats of kiwi spray (leather protect) on the vachetta to help prevent water and dirt marks, and clean it occasionally, then respray. But marking or dirtying the vachetta is inevitable. So then you have to clean it off.... again.
I also have a small line of colour transfer on the bottom of my hampstead - where the bottom has rubbed against the top of my jeans.
Overall, I think this will be my only azur purchase. Its nice for summer - but with all the issues, I don't think I will buy another azur bag.
