When in Rome, do as the Romans. Try not to look like a tourist. You'll be an easy target for crime and you won't get treated as well. I did a lot of research about how to dress and act. No printed "American" tshirts and NO flip flops. Italians take pride in their dress though simple. Nicer shoes and nicer jeans or pants. I actually packed for my husband. I didn't let him take his tennis shoes. He has a nicer pair of walking shoes. I bought kitten heel...
