Leading on from the school hat theme to a straw hat theme we have the boater which was a common part of the British, United States and South Africa and a few others boys school uniforms.
The Straw Boater is also known as the simply the Boater, plus the Skimmer, the Cady, the Canotier, the Basher, the Katie, the Somer and the Sennit.
Also worn in Japan were can be called the Can-can Hat or the Suruken.
The straw boater is equally a fashionable women's hat.
Straw boaters are a great summer hat, they were popular in the 19th and early 20th Century but have since gone out of fashion except for rowing events or barbershop music groups.
The Straw boater is normally made of a stiff sennit straw and has a flat crown and brim, usually with a ribbon around the crown.
A fact from Wikipedia says they were supposedly worn by FBI agents as a sort of unofficial uniform in the early 20th Century.
