Calling all Chanel experts, I really need your help!!! I'm reallying wanting a Chanel (my first) and I think that I would get the most use out of a tote as I like large bags with shoulder straps. What is the difference between the Cambon Tote and the Caviar Tote? Do they both have zipper top closeures? Feet? What colors does the Caviar come in? There are wonderful pictures of the Cambon tote and I really like it in the beige and black, but would it get too dirty? I'm tough on my bags. Thanks in advance for all help and information!
