For me, it's not so much what we wear, but when we wear it!
When we are on the Airplane we need to be identified as a Crew Member. When we're walking thru the terminal it is nice just to be identified as another passenger.
White Pilot Shirt with appropriate Rank, Black or Pink Tie, Black Slacks, Black Shoes and Socks. Simple and easy to dress when it's dark and your only half awake.
Oh, pay us $5 per hour more and we will buy and maintain our own uniform. Save the company money and increase our profit sharing.
