I think deliberately going grey (as in the Going Grey, Looking Great! crowd) can be a feminist statement.
I was really fat at the end of a 4 year undergraduate degree. Too much booze, not enough activity - standard student stuff. I started getting creaky knees and being embarrassed at how unfit I was. Over a year I slowly and safely lost the weight and got fit again. Politically, as feminist, and as someone sickened with most of our visual culture, I had problems with the idea of losing weight. In the process of losing it, I realised that I'd had problems with food which had made me gain it, I just didn't know about them. Lots of male friends became suddenly more interested in me, which was weird. I mean - if they didn't like fat me, why should I trust them with normal-sized me? They were given short shrift, but it opens my eyes.
But the thing is, life is easier if you fall broadly within the norm. It is good to recognize the difference between 'just feel good about yourself as you are!' - the political/playground stance that is recited about what's on the inside that counts - and the actual (cold hard) truth. That's my point I suppose: I lost the fat because I realised that people say one thing and do another. I was being told that despite the fat, everyone loved me. I was seeing the opposite. I lost the fat, and guess what? Hunch was true. People in general like you more, the more they like the way you look. The world shouldn't be like this, but it is.
So if, in this world where it helps if you fall within the norm and the norm values youth, equating youth with beauty - if in this world you could decide to look artificially young and choose not to - then you are picking your battle quite carefully, and you might well be doing so for a feminist reason, and I applaud it. I've decided not to colour my hair. I've been going grey since I was 22, and I'm still not very grey, but it's becoming more visible. I have a good haircut and I keep it maintained neatly and glossily, because I love my hair... but I'm not going to dye it.
Being fat made me unhappy. Going grey just makes me foxy.
