Fascinating and very informative. As MoD civilians attached RAF Nicosia 1961-64 we were sent to a Nicosia tailor for complete KD kits at own expence. The shirts, shorts and KD longs were of superb material, and lasted me well into the 1970s in UK. Socks were long and khaki wool, with white longs as a flashy alternative. No tie ever contemplated.
I remember Mick Martin, the staish [of 617 fame] asking where Met. got their gear.
This would be as he was cadging yet another fag whilst pretending he wanted a briefing. The office kept fags and matches handy, with him in mind.
The SWO changed his KD at least once and often twice each day.
