The United States Air Force uniform is the standardized military attire worn by Airmen of the United States Air Force. Specific Air Force Instructions address standardized wear that is identical for both members of the Active Component (i.e., the Regular Air Force), and that of the service's two reserve components that comprise the Air Reserve Component, that being the Air Force Reserve and the Air National Guard. Provisions are also included for authorized wear on certain occasions by honorably retired career members of the Air Force, to also include retirees of both the Air Force Reserve and the Air National Guard.
Wear of modified versions of the Air Force uniform is also authorized for the service's civilian auxiliary, the Civil Air Patrol, provided its members adhere to military grooming and modified weight standards.
Proper wear of the U.S. Air Force uniform is outlined in Air Force Instruction 36-2903 (AFI 36-2903), Dress and Personal Appearance of Air Force Personnel.
