It seems to be the way it is.
As a retired HoD in teaching, and in Modern Languages, I can count on one hand the number of male colleagues I had. One - of Italian extraction - was particularly fussy about about what he wore. The rest were like me - wear what you have, including the women, and none was ever anything less than professional bar one, with whom all I needed was a quiet word in her ear, so I don't get this need for ongoing wardrobe challenges.
Even the BBC weather women - I'm secretly in love with Carol - tend to wear the same thing every few days. So why do the TV racing women feel the need to never wear the same thing twice? Is their wardrobe allowance so generous, or is it a contractual thing, supported by a generous wardrobe allowance?
And why the fvck are we even discussing such trivia??
