I want my 2nd LV bag. The first one was a Speedy 40. I didn't like that I couldn't carry it on my shoulder. I sold that one. This next one must be able to be carried on the shoulder, it must be large (which they both are), and it must be sturdy. I know that many of you have these bags. Which would you recommend for an everyday work bag? My first instinct is the Neverfull, because I don't want the bottom of the bag to look dirty on the leather. Please give me your honest opinions...Thanks.
