I know what you mean, but as long as they do the job OK why worry?
Photo taken at Gan in 1958 (42-miles south of the equator) , so it must be hot!

OK it's 13-years after your WW2 stint in the Far East, but this 1958 photo pic shows how elegantly sartorial the RAF Nav wearing his white flying overalls of this Ceylon - Gan air-bridge Valetta is compared to his RNZAF counterpart wearing KD with slacks under the wing of the RNZAF Freighter at Gan as seen in the photo at the bottom. I assume the individually "tailored" white flying overalls were Changi village specials.
Compare with Sgt Henry Moon NCO i/c ASF Gan as he greeted the arrival of the aircraft c/w with greasy rag and probably a spanner in his back pocket!
