Take the alma bb! In 2014 when I purchasen my first luxury bag I was also considering between the alma bb and celine nano luggage, and ended up with the alma. No regrets, I still love almas siloutte, it is so versiatile, you can dress it up and down and it fits actually lot more than you would first think. I don't love the nano anymore like I used to, but alma will always be in my heart.
Besides there are so many options with the alma bb, you can buy it in canvas, epi leather and in vernis leather, and those are all durable materials. My alma bb was in black epi leather and I wore it many years daily and was so rough with it and it still looked great. It has seen a lot of snow and rain and in a bar someone spilled a whole drink on it and it survived all that still looking like new. It is so durable!
