I have a Bayswater in black antique glacé leather, it's a darwin leather that was treated with heat on the surface to create the shiny finish. The glacé leather is more waterresistant than the regular darwin. I'ts also a bit stiffer when new, due to the finish, but will soften when used. I'm very happy with this bag, use it as my everyday briefcase /tote for work and can fit my laptop, a notepad plus a book into it, as well as the necessary stuff like wallet/phone/lipstick/keys. There is a small zipped pocket inside where you could put keys and a lipstick, but hardly your wallet - unless it's tiny. I prefer a larger, more clutch-like wallet for this bag, where I also put my cellphone, as there is no pocket for cellphones in the bag.
I normally carry it over my sholder, but if I have a lot of books, I carry it in my hand and bring an extra shoulderbag for wallet/phone etc.
The best thing with the Mulberry bags is that they get better with use - the leather only gets more soft and beautiful.
