The Sonatine definitely does not fit over the shoulder. But it is a STUNNING bag and I get many compliments on it. I actually think it may have been discontinued and what is left in the stores is it!!
I love the Sonatine. VERY classy bag for going out. You don't see it nearly as often as a pochette and very seldom see fakes. My pick is the Sonatine head and shoulders over the pochette.
