Standard clothing has obvious iconic and functional features, and is designed to reflect the wearer's identity, position, rank, or the characteristics of the organization to which he or she belongs. Formal dress is widely used in a variety of settings, such as schools, companies, government departments, the military, medical institutions, airlines, the hospitality industry, and law enforcement agencies.
The purpose of uniforms is to reinforce organizational discipline, establish a professional image, facilitate management and identification, and at the same time be a part of culture and tradition, sometimes with ceremonial and aesthetic functions.
