Kepi, also known as kepi hat, was introduced back in the 19th century and is characterized by its flat top and sloping sides that meet at the front. It is a cap traditionally worn by military men, particularly in Europe and the Americas. Similar headgears that can be used as synonyms for kepis include forage caps, fatigue caps, army caps, and service caps. Variations of kepis also exist, such as the French kepi blanc and the ceremonial kepi used by police forces. Regardless of their specific styles, all these caps serve as a sign of respect and authority for those who wear them.
