Original WWII US Navy WAVES service hat for enlisted personnel. It is marked size 22.
It is in fairly good condition with some wear / wrinkling. The white crown has some discoloration (it doesn't show well in the photos, but it is there). I have not tried to launder it, but I am fairly confident it could be cleaned and made a bright white again. The white cover snaps in place and can be switched out. There is some dirt on the blue brim on the inside. It is slightly misshapen from improper storage.
