I cant imagine Boris in a jumpsuit tbh.
However, why couldn't a female prime minister wear a jumpsuit. Or even gender free/fluid prime minister wear one?
And most people, men or women, dont dress for their day thinking 'what would the prime minister wear?'
There are lots if feminist issues around clothing. The fact that you like a trouser suit and they arent currently widely available, because not many people wear them isnt a feminist issue.
It actually makes getting back into work easier and cheaper.
I was just thinking about my return to work 3 years ago. Style and beauty section helped me. In fact, they were the ones that said to take note what women in my city wore as well as recommending interview and back to work clothes. I dont go there often. But there is excellent support there. Especially for women, getting back into work.
Had 2 promotions since, I returned to work and going for my third tomorrow. Lack of a trouser suit hasnt held me back. Far more things in the work place would hold me back, as a woman. Not wether I own and wear a trouser suit.
So for me, the lack of trouser suit availability isnt a feminist issue. It's a fashion one.
