A type of Hat worn by female Flight Attendants. It generally has a round shape, fold-over flap all around the sides with rounded crown that's usually also dome-shaped.
The flap around the sides usually slopes toward the front where it is parted. The crown can also sometimes be indented or otherwise round but not dome-shaped.
This tag does not apply to other hats also worn by flight attendants, such as Garrison Caps or Pillbox Hats. A flight attendant hat usually has a rounded, dome-like crown, while a garrison cap has creased or hollowed crown and a general triangular shape when viewed from the front.
