In case your hat becomes misshapen from shipping, here is how you can mold it back
Use a domestic iron on the steam setting or any traditional clothes steamer. Steam
the outer and inner sections of the hat until warm and slightly moist to touch. Make
sure the iron plate is about 10cm away from the hat; Don’t let the iron directly touch
Wait till the areas become damp and malleable. You can then smooth and reshape
any imperfections with your hands. To repair the brim, apply a heavy object to flatten
Once you have restored your hat to the desired shape, you can just sit it down and let
it dry naturally.
