Bicorne

Most generals and staff officers of the Napoleonic period wore bicornes, which survived as widely-worn full-dress headdress until the 20th century.

The French gendarmerie continued to wear their bicornes in the classic side-to-side fashion until about 1904, and the Italian Carabinieri still do so in their modern full dress.

It was also worn during the 19th and the early 20th centuries by civilian officials in European monarchies and Japan when required to wear uniforms on formal occasions.

A cockade in the national colours might be worn at the right side (French tradition), and a plume might be attached to the top (British military c. 1800).

The bicorne also formed part of the historic black and red full dress of cadets at the French Military Medical School (École de Santé des Armées) until this uniform was withdrawn in 1971, except for limited use on special occasions.

Until World War II such uniforms were worn by even junior embassy staff but now survive only for ambassadors in a few long-established diplomatic services such as those of Britain, France, Sweden, Belgium and Spain.

[citation needed] The Italian Carabinieri wear a bicorn with points sideways with their full dress uniform.

The uniform of a Field marshal of the Imperial Ethiopian Army, which was used during the early 20th century by Emperor Haile Selassie, had a Bicorne which was specially adorned with a golden lion's mane.
