As both a BV and Celine fan, i think the Triomphe might be slightly more functional for traveling and for ease of day-to-night use. The small Jodie is pretty much the most comfortable bag I’ve ever owned, and I think Fondant is a versatile color. It can certainly be used year-round. However, I personally would not limit myself to shoulder or hand carry only while traveling. I like the security of a crossbody option.
But wait - are you talking about a bag you will buy in Paris? Not necessarily the bag you will exclusively use in Paris? If so, and you don’t have a small Jodie, then YES! Go for the Jodie. Especially if you already have some type of medium crossbody bag. Jodie is so wonderful and comfortable to wear.
Sorry for the confusion, I think I mis-read your question initially.
Let us know what you decide!
