How about 'what not to wear?'
I remember one summer a memeber turned up to fly a Grob.
He got into the Grob with his passenger and just about managed to close the lid.
What was he wearing? A flying suit, RAF boots and - yes - an Irvine jacket. It must have been 25C.
Wot a pratt. I bet his passenger was impressed too...
On a serious note - he was overdressed and I am sure took a risk just to look - well - look a pratt really...
Same guy turned up at the PFA Rally dressed the same. Guess what he turned up in? A Peugeot...
Somebody else I know - a basic PPL with a spamcan - strutts around with 4 gold bars up - white airline shirt, shiny black shoes etc. Another Mitty. He was at N Weald Aerofair.
Thirdly - go to any fly-in and watch those struggling around on a hot day in flying suits and jackets when others - 'normal' in my book - are wearing more appropriate clothing.
THe point of it all is this - overdress at the risk of your cred. If you are fortunate enough to fly something that requires an overall - try to avoid the temptation to award yourself wings and cover it in loads of badges.
Arrive in the right machine - no problem - arrive in a 150 and watch out for the 'wxxxxr' gesticulations behind your back.
What do I wear? Shorts,T shirt and dekkies in my Robin - fireproof suit in my vintage 'Cabrio'. No fancy badge or wings either...
