is there a LV bag that u just couldn't live without??

Not a bag, but I always have to have my azur mini pochette because it holds my makeup and other miscellaneous items, plus a wallet, and my key holder. Sadly I don't get a lot of use out of my bags when I'm in school, but I would say that I'm always glad to be able to pull out my cabby on rainy days and my Nimbus PM as my "wow" bag.
 
My dad got me a Monogram Matte (sp?) tote for graduation almost 6 years ago. I have been wearing it to work almost every day since (and it still looks fab!). For sentimental and practical reasons, you would have to pry that bag off of my cold, dead hands.
 
BH, I just love this bag. It has such a great look and shape and so easy to use. I have a silver Dentelle one. Love it so much I have even though of buying the mono one as well. I hope they make it in another print soon.
