I understand that modern outer layers are more functional. A leather jacket, for example, can be dressed up or down so as to be worn in a variety of situations. It is also better at keeping you warm.
However, I think capes/cloaks are more aesthetically pleasing garments. It also feels good to have the fabric flowing around you as you walk. But what do you think?
Mostly because my cape is improvised and I need something to hold it in place, which usually means my pauldron, but I only wear that on special occasions. It also sheds a lot of lint.
