I have a Divino in Bordeaux, and I feel you're right about the shoulder drop. It's fine during summer (it's summer now in AU) I haven't had it long enough to need to wear it over a winter coat but when that time comes around I'm pretty sure it'll be a satchel. Also I have problems with it slipping off my shoulder when my hands are full of grocery bags, but I tend to have that problem with all bags.
That being said, it's a gorgeous bag, gets lots of compliments, unique style, gorgeous color, and I haven't had mine for very long but it appears to be pretty solid and durable.
The leather is a smooth, thin-ish, very finished leather that's crinkled, it's not that uberluxe smooshy soft leather, but it's nice. The handle and the strap that keeps it closed have a really nice ribbing, but the zipper pulls are just leather tags which I'm not too fond of.
I know I'm sounding really negative, but I do love this purse, but it's not an everyday bag. It dresses up a pair of jeans when you're wearing heels, and it's great to take to work, and it's a lot more roomy than it appears. The lack of structure does make the bag sorta expand, but then it destroys the shape of the bag, and it only expands for lots of small stuff, you can't toss a sweater or anything in it.
The biggest cons for me are that I don't think I could wear it on my arm over a coat, and that it loses structure when you set it down. If you can live with that, by all means, get this gorgeous and unique bag. I've really never seen anything that resembles it, and to me it has a sort of timeless look.
