I think of a Part Time as being *less* structured than the City ... because of how it collapses so much in the middle because of it's width (combined with smooshy leather). Because of this, I actually think the City looks more elegant when being carried by the shoulder strap. I guess it depends upon how you like to carry it. I agree that the PT might look more structured than the City if you are carrying it by the handles. I just hardly ever do that, so that's probably why it struck me as odd to think of it as more structured...
