Always open, but trying to learn to shut them, because as I carry my 18 month old on my hip to the car, her foot always gets caught in my LV open bag and everything always comes tumbling out as I transfer her to the car! I was so proud of myself yesterday cos I remembered to zip up!
I always carry all of my bags shut. Otherwise it would be an invitation for thiefs (at least in m mind). The other reason is, I don't want things to get wet, when it suddenly starts raining...:shame:
