You guys can fight out the appropriateness or not of this being on a pilots' site...and whether or not the economic times should permit the expense of a uniform change.
My contribution is that we QF cabin crew wore white jackets on the aircraft at all times when i started. Good deal too..took them off after each sector , bagged them up for return to Sydney...every time we got on an a/c there was a nicely cleaned and pressed jacket in the coat locker with your name on it.
God knows what that all cost!
