When I was an army cadet, we were strictly forbidden to wear any part of our uniform or kit unless we were 'on duty'... so no wearing it to weddings or other unofficial functions to impress the birds.
Also, I had a mate who thought a WW2 Denison smock would look good over his denims (fatigues)... that was until an old guy stopped him one night and tore into him, mainly because he'd left the Para's wings on the shoulders.
