Funny isn't it, pretty much every other sport or hobby has its 'garb'. How often do you pass the Tour de France or IoM TT racers on the way to the airfield? Or how often do you find the Saturday 5-a-side team playing in cargo shorts and a South Park T-shirt. As for golf ...
Yet anyone who feels it's sensible to wear a set of overalls let alone a genuine RAF surplus Nomex gro-bag is considered a poncy show-off wanna-be jet jockey.
Afraid the inverse snobbery where the only acceptable clothing to fly in is a pair of Supermarket jeans, a market stall bargain bin T-shirt and a pair of sandals is laughable and quite pathetic.
What are you trying to prove? That you're 'normal'?
Those who I see wearing their oil-stained gro-bags sitting in my home airfields cafe I think 'good on you'. My wife would certainly prefer I wear a set rather than getting grass stains, oil and crud all over my TU jeans as it just makes more work for her.
