I have the smaller version in blue patent and it's already pretty big, so I'd imagine the big basquet would be HUGE. Like bagachondriac said, the patent is pretty stiff and not really collapsible, so it's a little awkward to carry over the shoulder. I don't know if the big one has a longer strap drop, but because of the shape I can't really carry on the shoulder without my arm sticking straight out like I'm holding a bowling ball under there. It's also a little on the heavy side (surprising, since there's almost NO hardware on it).
It's really a stunning bag, though. If you decide to go for it be prepared to get stares and have women following you around just to look at it!
