Seems to be an awful lot said about what people wear or ought to wear on pprune! Personally I couldnt care less if a PPL dresses like Admiral Nelson. If I recall correctly the ATPL does not have a ratings page that includes the right to adorn 4 gold bars any more than the PPL one does! Those with the vanity issue are most likely those who look at themsleves the most in the mirror...
'All men dream; but not equally. Those who dream by night awake in the day to find it was vanity; but the dreamers of the day are dangerous men, for they may act their dreams with open eyes, to make them possible.'
