The first flying school I worked for had 2 pages of A4 plus illustrations on how to wear the uniform, including the name badge, bars, tie, jacket, NATO pullover (all company supplied). You had to provide white shirts (2 front pockets and epaulettes) black trousers (with crease down the front) and shiny black shoes. We had to get permission from Head Office to remove the tie in hot weather. There was a strict pecking order for the number of stripes on the bars and their thickness. But then, they were paying me a salary plus bonus if I flew more than a certain amount per month.Then they went bust. Haven't worn a tie or bars since.
My old club used to give out wings with the club emblem (a Lapwing) in the middle when people got their PPL. There was only one bloke who actually sewed his on to a jacket (sniggers behind his back).
