Yes! I actually saw some blokes at the PFA Rally on Friday in black trousers and white shirts with epaulettes! One 4-bar, several 3-bar and one 2-bar.
I didn't see what they were flying, but there were no airliners there that I could see.
Didn't see any pilots in Babygros, though.
Friend of mine who's flown in Africa says it's important to wear epaulettes there. Doesn't seem to have the same effect at Popham or Cranfield.
