Grob Queen - that's fine when you're operating in a military environment. When you go to any normal GA airfield, you'll find that the only people wearing gro-bags are the aerobatic lot, as a rule. And they only wear them for aerobatics. Be prepared for funny looks and sniggers at a number of places, some better hidden and polite than others. I remember being shocked when I first joined a civilian club and realised that people just don't wear gro-bags except for specific purpose. But I soon got over it, at about the same time as I got over using a yoke instead of a stick.
It's a personal choice as to what you wear in an aeroplane, but as someone else said, really you should wear a bone dome, gro-bag, gloves, boots and the right undergarments. And while you're at it, how about a parachute? I use all of these for performance aeros. But I wear jeans and t-shirt for straight and level PA28 / Cessna / yawn type flying, and I'm quick to take off the gro-bag as soon as I'm done fun flying.
Someone said never to wear a badge unless you've earned it. This is so true. I have a name badge which is relevant in some circles. But on home turf, where everyone knows me, I never wear it.
