Unique headgear all use the same icon

It appears that all the unique headgear are using the same model.

Can you show examples?

I don't know about all of them, but it was a little weird when I found a "dandy" unique hat that in inventory, looked like the brown striped cap helmet, but when you put it on, it turns into a slightly altered version of the wide brimmed feathered hat.

also, the hat that is a monocle (the one with the will boost and charm cast) also has the standard helm icon.

but no, not all of the unique hats have the helmet icon.  enough of them do that it might indeed make someone think so though.
