I disagree it's a womens issue.
Office wear in the uk has made a huge shift for both men and women in the last 5 years.
2 piece trouser suits, for women, are less popular.
I work in HR for one if the uk arm of one of the world's largest employers. Office wear here and in the US head office is definitely more casual smart.
And it is the same for men. Men rarely wear a 2 or 3 piece suit anymore.
Senior managers and directors (female) wear dresses, jumpsuit, trousers with smart tops, suit jackets usually over Jean's and dresses or casual trousers.
So they are more difficult to get hold of in high street stores. You need to go to more specialist shops.
Yes women can struggle as they are more likely to spend a few years out if the work place. But I did a bit of online googling of more recent fashions when i returned 3 years ago, after 4 years off. Also kept and eye out when put in town to observe what women wore.
It doesnt become a womens issue, because you want a suit which is no longer the main stream fashion. If you like them, wear them. But they will be harder to get hold of and you cant force then to be in fashion
