I am currently considering the McQueen Novak black leather bag that has python trim and detailing (the python is also black). Unfortunately I do not have a picture of the bag; it is quite structured though. Do you consider a combo bag as such a dressy/formal bag? Or a more casual rock-and-roll style bag? I want to be comfortable using the bag in jeans but also in a dress and heels. What do you think? Would I be limited in my options? Or can I pull off both styles? Opinions would be greatly appreciated.
