is the drop long enough to fit over the shoulder? some of my bags with a similar 7" drop are OK others are not. anyone with modeling pics? I am thinking of returning my large camel leather carly for this one, it would be my first lily and I think the size is just right! plus, and please someone correct me if I'm wrong, but it looks like the turnlock strap thing does not go over the whole purse, meaning I can unzip either of the sides without undoing the strap right? TIA ladies!!!!!!!!
