Era dependant head acesories/hair

Some hairs and hats just look silly in some ages, I like how my avatar change clothes, and hats where other an important part of king/leader insignia or just fashion. I would like to have an option to give my character hats or some features like eyeglasses, but in a way, so they don't stick out in some eras.

Now we can unlock various symbols that represent our faction, maybe each culture type receive 1 hat for each era that we could add to our leader that would change by era, 3 types of glasses, modern "normal" glasses, monocle and wooden glasses for medieval/renaissance.
