This thread is beyond the realms of immaturity I thought even the newest and youngest Pruners were capable of.
Oxford is a proffessional outfit, you work, you win, you don't work, you lose, big time.
Now given the £25 outlay for epaulettes, shirt and tie (the only compulsory items, surely everyone one the planet has black or blue trousers) I think that the cost does not even factor into the £40-60k you'll be spending on flight training at OAA. The shirt needn't be an OAA one so that rules out the advertising, and as for being mistaken for a policeman, well, if that bothers you.............
Now as for the need for the uniform you'll be hard pressed to find a good institution that doesn't have you wearing it at some point of your training, and its the same winy fools complaing about this uniform, that would be pointing at Tom Dick or Harry for being too smart, too flash or too scruffy if there wasn't one.
Get a life.
