Those that know me will be aware of my anti tie stance. Apart from a personal dislike of the affore mentioned garment I dont think it makes pepole look any smarter or authoritive, its all in the mind.
Some people wear suits and ties for everything and they dont look any more smart than the bod who wears clean and tidy casual clothes, in fact some might think that people who wear uniformaty type clothing may lack personal image thats why they follow others (just an opinion right or wrong?).
As for the dress code here we have a mix of tie with suit, tie with shirt, no tie I think all our staff have equal smartness and all are capable of displaying the brain power to dress themselves without the need for militarian uniformaty.
