A space saving Top Hat
An Opera Hat, also called a Gibus or Chapeau Claque, is a collapsible Top Hat variant operated through a spring system, originally intended for less spacious venues, such as theatres and opera houses.
Opera Hats are typically made of black satin and fold down vertically through a push or a snap on the top of the hat for convenient storage in a wardrobe or under the seat. The hat can be opened easily with a push from underneath.
