AC ovee,
So only senior officers dress in a smart and appropriate manner in their messes? Tell that to the Marines, as the old saw has it! Most of the senior ranks messes to which I have belonged had a strict dress code which no-one was allowed to break. I did visit an RAF senior ranks mess one evening and was confronted by a pair of aged old buffers wearing open-necked shirts and slippers, so there may well be a problem peculiar to the RAF!
