A neck order is a type of decoration which is designed to be worn and displayed around a person's neck, rather than hung (draped) from the chest as is the standard practice for displaying most decorations.
Most of the insignia of orders are issued in several degrees which typically include a neck order version for Commanders and Grand Officers. In countries which do not typically bestow orders with degrees, neck orders are still usually considered to be high-ranking decorations.
In the Middle Ages most orders were worn on a collar – see livery collar. Later, in the 17th century the insignia were worn hanging from a ribbon around the neck. When, in the late 18th century, orders were divided into several classes, the cross on a ribbon around the neck became the privilege of a commander. A decoration in that rank is usually awarded to high-ranking officials like brigadiers, consuls and secretaries of State.
A female usually wears her commander's cross on a bow on the shoulder of her dress.
In the 19th century it was not unusual to wear a Grand Cross, normally hanging from a ribbon over the shoulder to the hip as a neck order when this was considered more convenient or when another Grand Cross was worn.
