I completely agree with you on that, so I’m really not intending to argue.
But the breadth of a woman’s inner world - her likes and dislikes, fears, anger, sadness, hopes, dreams, intellect and passions are on an entirely different level to her physical attributes and ‘looking good’. They exist independently, and, at least in my case, will come through loud and clear regardless. I value that inner part of me far more, always have, and will always be of the opinion that if others don’t, they can fuck right off.
However I can plaster a big beautiful smile on my face if I need to, claim a room when I walk into it if I need to, talk animatedly and be intensely engaged with an individual or a group if I need to - just like I can put on a fantastic coat or great shoes or a striking hat and make a very clear and deliberate statement when I want to, without it taking anything away from me as a person or my authenticity as a feminist or my ability to be true to my inner self.
I had thought that OP was looking for tips on how to look good. I answered because there’s nothing wrong with wanting to look good. But to be honest I find the whole idea that we need to ‘look good’, first of all, but more specifically that we must ‘make the best of yourselves’, ‘dress in a way that flatters you’, ‘only show those parts of you that fit the attractiveness ideal’, ‘age well or you don’t count’ ‘don’t age or you don’t count’ and frankly, most things related to the tyranny of fashion and particularly in respect to ageing, utterly rage inducing. I rebel against them more than I ever fall in with them and hence, spend a LOT of my time angry at the narrative(s) we’re all made to swallow in that regard.
But I still enjoy fashion, i still like feeling good in what I’m wearing, I still wear make up sometimes (when I can be bothered). I still like my hair to look good and my outfit to make a great impression. That’s part of who I am. In many ways style is substance, as I’ve argued many times before on S&B/feminism/wherever the topic comes up, and although I rebel against the overall narrative, I am free to enjoy whatever elements I want without it compromising my position on the ills of fashion or the ills of female oppression.
Smiling is similar. Of course I don’t owe smiling to anybody and of course I don’t need to be some bloody smiling robot, but OP was specifically asking how to look good. I quite naturally and organically smile when I want or need to be ‘on’, because it’s an important part of looking your best/looking good/whatever you want to call it. If you want to look great a smile, and with it, an engaging manner, helps a lot.
If the above has no coherent line of thought or clear conclusion to it it’s because today is my 7th day of being ill. I know what I want to say but I’m not sure I got it out.
In any case, OP, if you don’t want to smile when you’re not in the mood, you don’t need to.
