After seeing a lady carrying a gorgeous patinaed noe, I've become obsessed with LV bags. I can't narrow it down to which bag to buy. I'm between the vertical batignolle, vertical lockit, petit noe and mini noe. My only "against" for the lockit and mini noe is I would need to buy an extra strap to shoulder carry them -- a must because I have a 3 year-old and infant -- and they don't seem to be available anywhere in the US. Any thoughts?
