Flight attendants and Cabin Crew have long been the face of the airlines and are expected to have high standards of presentation. This is partly for safety reasons and compliance, but also for professional discipline. It is also important for brand identity, so that the uniform often becomes synonymous with the airline. For example, the Emirates red hat with cream scarf, beige suit and Singapore Airlines iconic kebaya are among the most famous airline uniforms and have not changed for many years due to their popularity.
