I was leaning towards the bag with the detachable strap......my only concern is that after a while I might get tired of having the short and the long strap on the bag. Now, that is the look on many bags, but what about next year? Should I be worried that the bag will look dated?
I'm tall so I prefer the top handle with strap version (middle pic)...I like how it hits me on my lower hip when worn on my shoulder. I get tired of bags that don't fit on my arm or if they do it is a tight fit.
