In college, there was a guy everyone affectionately called "The Capeman." He walked the streets and the campus (I'm pretty sure he was a student), and was always wearing a long, black cape. You might see him on a Sunday morning, coming out of a coffee place, in midday when it was over a 100 in the summer, and he'd be wearing that cape.

When you see someone wearing a cape, you have to wonder how did they decide that a jacket or overcoat was just too confining? Does a scarf or shawl not have enough "punch" they need for dramatic entrances? Where do you even buy capes? Do they rate the amount of flow each cape may contain?
