I personally don't like the look of the Nano Luggage, that's why I only own a Micro Luggage. I just prefer the Luggage style in the bigger sizes. As for the Belt Bag, I did at one point own two of them because it's just such a gorgeous bag. I don't think it's trendy at all, in fact, I have never even seen anyone ever wear the bag in real life. To me it looks classy and chic, it doesn't scream any logo and if you don't know about Celine, you won't even know the Belt Bag is designer.
