Just to throw in my few pence worth - I received one of the cotton lighweight jackets for a prezzie a while ago, and have found it most suitable for throwing on for driving down to the shops at night. Always concerned about its fuel-resistance, it stays well away from light aircraft.
As for the 'naff' embroidered wings, I paid best part of £3,000 for my licence. All my savings, etc, etc - so I don't mind people seeing what I've acheived.
