I'm 5'5" and if the strap was any shorter, it'd probably be too short for me:
I have been back and forth and back and forth and back and forth SO MUCH on the nano. I (think), for me it is a no, for now. I have to ask myself the same question before expensive purchases - do I think i will wear it in 10, 20 years? For the nano, I don't think I will. Though it is eye-catching and unique, I just think it is too cutsie for me personally, so I can't see it aging well with me. It's sad in a way, because I really was in love with it for a long time.
I posted this on this thread and almost four years later I finally bought one! What can I say, you love what you love. I'm not going to be the type to follow the hype or trends. If it's beautiful it's beautiful. I absolutely love the bag and don't regret the purchase. I've been using it regularly since I bought it, and almost every day since the pandemic started (it's a great pandemic bag). It's such a unique design and it's so functional! I love it so much I now want a mini luggage! It's an iconic bag.
