The Burberry idea has a bit of a flaw, apart from looking like a

-witted chav loser, the CAA would be forced to update R/T procedures if it were worn by pilots.

For example:
'On base, innit'
'Want flight information service dun-I, ya know wot I mean?
'I aien't sqwalking

all mate, you sayin' I dun summat wot I aien't not never done right so shut up'
'Wot? I wanna land, I know my rights'
'I don't haf'ta get clearance right cos my mate said he never done so an' he knows it all and you're just fick an' don't know nuffink'
'Traffic in the vicinity? Do I look bovvered?'
And of course:
ATC:'Are you ready immediate?'
'No, but yeah, but no, but yeah cos I got off with Chanice cos' Brittany woz chattin' up Ryan & Keanu an' I called her a slapper & stuff'
Personally, if I turned up to fly my friends in anything other than my usual scruffy-ass style, they'd a) Worry & b) Probably laugh.

As for wearing ties, they are for sad occasions only, funerals, wedding and job interviews..........
