In fact I would say that some of the supposed wins of feminism were really about middle class solidarity rather than anything to do with feminine solidarity.
For example the Suffragettes.
At the time there was huge trade union activity. Coal miners, mill labourers, the industrial districts. Millions of men and women on the march, strikes. A real struggle for much needed better working conditions, wages and housing, employment laws. This is overlooked now in favour of a handful of London middle class Edwardian Vannessa Redgrave types, throwing things at (working class) police officers or tying themselves to railings because they wanted the vote for middle class women. Unsurprsingly, they had very little working class support at the time
I would say much more recently than that, for example with the entrance of middle class women into all kinds of jobs in the workforce, partiularly professional jobs. This has generally been seen as a win for feminism, and to some extent I suppose it changed how people thought about women in work.
But looking at the effects - that's important to understanding the basic story. In a family where the husband was, say, a lawyer, and now the wife could become a doctor, they are hugely increasing their economic power as a family. Even with childcare costs included.
For a working class family, it's entirely different. For one thing, often wives were already in the workforce. It helped to balance out the economic disparity compared to the middle classes, just a little. That's no longer the case once the middle class women are also in work, so the economic gap is wider.
If those women wanted to go into work where they needed to pay for childcare, the cost of the care wouldn't necessarily make it worthwhile. In fact many would be working in childcare for others (the middle class women who now needed carers for young kids.)
So those women were doing more of what they were doing before, rather than having a lot of new and fulfilling types of work. Factory work or secretarial work, cleaning, and factory work were probably the main options. All of which is good dignified work but you have to ask how many really felt more fulfilled doing those things rather than being able to stay home, even part time, to take care of their own kids and home.
They also were much less likely to b able to do similar kinds of work to their husbands, with better py than what they had been getting in what were considered women's types of jobs. No matter how you cut it, for women who are becoming pregnant, certain types of heavy work are not going to be plausible - they are not going to be on the fishing boat or down the mine, or going off to war.
So lots of advantages, economically and in terms of personal enjoyment, for middle class women and their husbands. But little, or even negative, economic implications for working class families, and the omen possibly losing the option of not working as they try to gain a little more buying power. So is that feminine, or class solidarity?
