Deliverance, old chap...
I'm just giving a civvie point of view - it doesn't look "right" (or "appropriate" as I used originally).
I could see, say, a fireman in his dayglo stripes stopping, hopping out of his cab and buying a pint of milk at the Co-op. But if he was in full silver asbestos suit, I would look askance!
On another thread, gentle banter was taken of a Spacey VR(T) in the mess in flying suit and RC wings - no problem with the banter - the dress was inappropriate (if nothing else!). But what's sauce for the goose...
