Try raising it with the RAF Uniform Clothing Policy Committee - or something like that. They work at Quedgely near Lyneham and the committee meets every 6 months. They have just met so the next one won't be until Dec 09/Jan 10! They are headed by an SO1, with an SO2, SO3 and WO and the obligatory civil servant!
There is also a thing called "Threads" on the intranet and you put all of your RAF uniform issues and suggestions on there. I think it might be a forum?
Good luck

PS. I agree with you and seeing as we have to wear TRFs and ROYAL AIR FORCE on our CS95 there would be plenty of RAF identity!!!
