If what you wear is a measure of who you are then according to the 'rules' espoused above Richard Branson (who never wears either a suit or a tie) shouldn't really be where he is, should he ?!
And what about Sir John Harvey Jones - a bloke more commonly known for his flamboyant suits and ties, than for his stewardship of the multi-billion £ corporation that is / was I.C.I. !
Ps. Come to that, what a about Big Bird (well, everybody has heard of him, right ? ) , e.g. ever noticed that it's nearly always the non-conformists who seem to be the ones raking in the mega-bucks ?!
