How about these two, posing at Marham and clad in something apparently left over from the Norman Tebbitt scenes in "Spitting Images".
My surprise that such a senior officer in the so-called Defence Intelligence world should apparently be unaware that he is so manifestly improperly dressed, and on a reasonably important occasion too, is only exceeded by my astonishment that it should be considered appropriate to wear the Royal cipher in such informal "uniform" as is referred to above.
The nearest naval equivalent to the first solecism is known as "going astern", namely wearing one's left shoulder strap on the right shoulder, and vice versa. Harder to spot than in the Air Marshal's case, since most people seem to manage to get the curl facing towards their head, but worth a drink to anyone who catches you doing it.
