Vogue and their advertisers know perfectly well that young activists - unless they're in possession of a trust fund - are not going to be buying these clothes. Hell when I was young I could barely spare the price of the magazine. They still need the custom of the affluent, most likely older, woman. They're trying to wave at one group while winking at another.
Well, you said this^^, which sort of implies their current demographic / market couldn't possibly afford to keep them in business and that you think, based on your other comments, that their trying to engage with these issues might put their current readership off. Well, I personally think this is overly simplistic. Fashion does not exist in a vacuum. The industry is affected by current affairs and has always been through history. I actually think fashion tends to reflect the times. So, clinging on like hell, to the old model, ignoring everything else that is going on in the world would actually make them out of fashion, wouldn't it? Fashion doesn't get decided upon by any particular group, so if they just did what you suggest older women like, they would end up out of touch with everyone else. Which would be foolish. My dad is nearly 70 though, (not at all into fashion), a high earner and very engaged in politics. I don't think it follows that older and richer = doesn't want to see this in their fashion mag. Just my view and all that.
Re posturing, well yes, it was always thus! But, for me, the fact that it's fashionable to be engaged in politics and especially social justice, is a good thing. Better than when it was fashionable to only care about making money, which is what I am told was the case in the eighties.
And fashion always has involved posturing. It's all about the image you portray and how you express yourself. So, I find it hard to shed too many tears over losing the old model for the fashion industry which was, what? Free of posturing? No, it never was. Maybe this actually will nudge fashion houses to be more ethical. But perhaps I'm being naive there. I certainly don't blame the new editor for trying to tackle these issues though, even if it is at least partially driven by profit and fashion...but then they're a fashion magazine, so of course they will be doing what is fashionable. Can't criticise them too strongly for that.
