Hey Ho,
My faher works for an international company that operates a G5 from the US and internationally. It came out to Aus (Essendon actually) and i got a look inside and a talk to the pilots.
I think the company agrees that the traditional 'blues' is a bit off putting, and wanted to make their pilots look a little more friendly.
Their uniform consists of a normal grey double breasted business suit, with subtle bars around the cuffs. Normal white shirt, and a company tie. I'm pretty sure they don't wear a hat... It looks just like the PAX are wearing (Except the bars).
I reckon bendo, that you wear your 'blues' whilst around your boss, and lose as much as makes you comfortable when in the aircraft... After all 'it is the responsibility of teh PIC to ensure that the aircraft is operated safely', and if you think your uniform may have even an ounce of a change at degrading your performance due to being uncomfortable, don't wear it! Your boss can't argue! He can prolly sack you, but he can't argue!
