I ordered the small, thinking it was the large. And was very surprised when I opened the Nordstrom package, lol.
So personally, I found it to be too small. Like Diana said, even without carrying a laptop, I found the small to be too small for my everyday items. Also, it felt funny hanging from my shoulder, kwim?
I don't think it looks too small, I just mean it felt small and not substantial enough for me - both in terms of size and function. And it was a lot of money for something so small and not practical for my life. (But then again, I tend to carry a lot in my pocketbook.)
What do you plan to do with this bag? Do you want to carry it every day? What do you typically carry in your purse? That might help you make your decision.
So I did return it back at the store, thinking I'd exchange it for a Large navy, but then I saw the Planetes and all else was forgotten.
