Fun fact brooklyn style caps came around 1860s, soo these kinds of hats would fit with the lore. It can be a skin for a top hat.
Another discussion is, should there be a way to change the appearance of tam o shanter hats? and krampus sacks with elegant skins?
For example, my friend bought a mandrake on klei store and wishes he should change the krampus sack into a mandrake backpack.
I suggest they add a tab for skins in the alchemy machine with items such as krampus sack and tam o shanter hat
I know it can be done, they did it with the prestihatitator.... mouth full >.<
