Debora-
I would say it depends on how big you are. I can fit mine over my shoulder and others here have said they can as well, however, I am 5'3" and very thin. Depending on your size, it may or may not be comfortable for you. I think it looks best worn on the arm, and it gives a funny shape when used with the shoulder strap. But it is very versatile if you need to carry it any of these ways, it can be dressed up or down, and it is beautiful.
