On which shoulder are most aiguillettes worn?

Most aiguillettes are traditionally worn on the left shoulder. This practice dates back to military protocol and distinguishes the wearer's rank and position within an organization. Wearing the aiguillette on the left shoulder allows for conformity and consistency within military and ceremonial contexts, making it easier to identify roles, such as that of a commander or an aide-de-camp.

Additionally, this placement aligns with historical practices where various insignias and decorations were placed on specific shoulders to denote rank. The left shoulder is preferred as it is the side that is typically most visible during formations and inspections, ensuring that the aiguillette serves its intended purpose of recognition and décor. This standardization helps maintain the formal appearance of uniforms across various service members.
