IT = some kind of "outift", certainly involving a band t-shirt which no-one cares about and, annoyingly for the wearer, many other people
have heard of. Amusing hairstyles and comedy shorts are de riguer and frequently discussed with, it has to be said, some of the more forthcoming IT oiks, if only for the more GQ man to give guidance.
Everyone else = Tailored suit, keeping IT oik in job, if only because bizarrely they're necessary (turn it off and on again? Is that a
job?)
Phew. I think I covered most of the stereotypical arguments, let me know if not
