The uniform is made from durable materials to withstand harsh maritime conditions and is often adorned with insignia that indicates rank and branch of service. The traditional sailor's uniform has evolved over time, with variations for different roles and occasions. For example, the dress uniform is worn during formal events, while the working uniform is designed for daily tasks aboard a ship.
