I love hand held bags like the speedys and I love the galliera pm b/c it's for the shoulder. But I want a med size bag that can be used both ways. I get tired of it constantly on my hand so my question is the tivoli pm comfy on the shoulder as well as it is in hand????What others do you suggest? I'm only 5'2" tall and slender so super big bags are out of the question....The galleria pm is the biggest I'll ever go.
