I've featured a Humawaca bag before - a backpack that I wasn't entirely sure about - but I definitely like this 'Lili' bag.
Described as a large day bag or small overnight bag, it's got a pretty flowery lining and I like all the leather detailing. It's also available in black and brown, but the white's the nicest (if the least practical). It costs £300.
