Hi all.. I am a working mother (have an 11 month old), and am torn between waiting on the Tivoli or purchasing the Trevi. I have quite a few bags, but I just LOVE both of these bags... I live in AZ..so it does not rain much, however, I do travel a little back and forth to Vegas for work... What would you all recommend?? I obviously will have to wait for the Tivoli, but I can't decide which one is better suited for me? Can you wear both bags over your body if you need to? I know they are both shoulder bags....I am thinking GM since I have a little one, and want to also use this for work at times.... I am in a very professional industry, so I don't want to be to overstated, but still classy.... HELP!!
