A beret is a type of HAT that is typically round and flat in shape, with a soft, flexible brim. It is usually made of wool or cotton, and is often worn as a fashion accessory. The term 'beret, for example' is used to refer to any type of HAT that is similar in style to the traditional beret. Beret-style hats have been popular since the 19th century, and are still worn today by people from all walks of life.
