Grief.
Surely aviation clothing unless it's practical is a waste of time, appearance is a bonus.
I freely admit to wearing a Nomex flying suit regardless of what I'm flying (it would be hard to deny most of this forum have seen me in it) and it seems a shame not to put an appropriate badge or two on it (name, wings, and ETPS in my case). If at my destination it is cold or muddy I leave it on quite happily, if it isn't I don't.
I do own a pair of Pprune wings, or at least I did - I think I've lost them.
Blue jerseys, gold bars, ostentatious wings - why? They are a uniform serving a particular function in a particular workplace. When I worked in a workshop as a very junior trainee engineer I didn't wear my overalls or white labcoat away from work, what's the difference?
I'll make one exception, a leather flying jacket (pick your style) is a pretty good universal garment - but I sure as hell wouldn't put wings on mine. It's as pretentious as wearing the badge of some highbrow society other than at it's meetings or using postnominal letters in any context but a professional one (okay, the latter can also reasonably be used to intimidate head teachers and council officials).
