and pyramids. One set of 24 were made three-sided, with "27 diamonds in the sides and one in the top", for a total of 642 diamonds in the set. Gallery Military usage The modern aiguillette derives from the laces used to secure plates of armor together—the breast- and back-plates would be attached on one side with short loops of cord acting as a hinge, and on the other by a longer and more ornate tied one, to support the arm defences. The ensuing knots would hang down the shoulder. (As with combat boots, the longer the lace, the less the need to undo the entire lace.) As armour became more ornamental and less practical, so too did the ties. This would also explain the aiguillettes of varying levels of complexity in the uniforms of the Household Cavalry (see picture above), as opposed to other "unarmored" troops. A version that says that aiguillettes originated in aides-de-camp and adjutants wearing a pencil at the end of a cord hanging from the shoulder has no historical base. Argentina Aiguillettes are worn on the right shoulder by armed forces officers serving in specific positions, such as aide-de-camp to the President, the Minister of Defense, each service's chief of staff and unit commanding officers, and by military attachés to Argentinian embassies abroad. The color of the aiguillette may be golden, silver or tan, depending the nature of the assignment. Olive green aiguillettes are worn with the combat uniform in very special circumstances, such as ceremonies and inspections. Otherwise, aiguillettes are not worn with the combat uniform. A special red aiguillette is worn by the adjutants to the commanding officers of the Horse Grenadiers Regiment (the presidential guard) and the Military Academy. Also, a red aiguillette is worn on the left shoulder by the senior NCO of each Army unit. A thinner, yellow aiguillette is worn on the right shoulder by NCOs who have completed the instructor course. In the Navy, adjutants to very senior officers wear golden aiguillettes on the left shoulder. Australia Aiguillettes distinguish officers of Flag, General and Air rank in specific command appointments, military attachés and aides-de-camp. Most senior officers and aides-de-camp to the Governor-General or state governors wear the aiguillette on the right shoulder, whilst military attachés and staff aides-de-camp wear the aiguillette on the left. Royal aiguillettes are of plain gold, naval aiguillettes are of blue and gold, army aiguillettes
