I note that often American commentators bemoan the (“too long”) length of Kate’s trousers, dresses , skirts etc but take no issue with her heels. I think it’s the footwear that distinguishes her from the current modes for professional women in the U.K. Skirt length aside, the POW still dresses in the way that was the norm pre covid for professional women of her age in the U.K.
From recent travels, in Canada, the US and Australia (no idea about Europe - would be good to know) women directors, bankers, lawyers etc still wear straight tailored shift dresses to knee or above, jackets suits and heels. This is an unusual look now in the UK and looks outdated.
In the U.K., my observation is that stiletto/ court shoes are seldom worn (replaced by brogues, loafers, kitten heels, Mary Jane’s and ballet pumps) and trainers are acceptable in most work environments. Dress lengths here are longer - mid length or longer and wide leg trousers are still more widespread than tapered straight leg ‘work’ trousers. Tailored shift dresses are never seen.
In my stuffy office, most women are back in more formal workwear but that’s likely to be tailored trousers and top with non matching jacket or a midi length skirt or dress often worn with flats or trainers.
