Ah no Adroight .. those were 'RAF leather flying gloves' (below) ..
.. which were in fact a very very light blue colour .. but looked white until they became soiled.
My godfather used to wear white cotton 'ceremonial' gloves (which I was also made to wear as a youngster). However he was not alone .. there were some who also 'picked-up the habit' such as the late great John Dicken!
