Aiguillette

An Aiguillette is an ornamented cord that is slung on the shoulder, hanging down on side of arm or chest. They end in gold metal tagged points, and are worn by officers to distinguish special and senior appointments.

The type of Aiguillette worn depends on the rank of the officer and/or the position or appointment they hold. The appointment also dictates which shoulder the item is worn. Most senior officers wear the Aiguillette on the right shoulder, while more junior officers wear it on the left. (Australian Army, 2014)
