The poll on whether you can dress well at any size closes early tomorrow, and I will be disclosing my own views on this subject.
Meanwhile I'm off to the hairdresser's. When I was talking to Louise Chunn about the mutton question, she remarked that she thought my hair was so much better than when she was commissioning me back in the 90s, when she was women's page editor of the Guardian. I think that the one thing you should really throw money at as you get older is the best possible hairdressing you can afford. The salon I go to, Richard Ward, does the make-overs for Trinny and Susannah, and indeed my own team of Mario (colour) and Roger (cut) do the hair of Trinny and Susannah themselves. The key to colour as you get older and greyer is to soften it and bring it in line with your changing skin tone. The original colour of my hair was dark brown, it's now warmer and redder and I rarely go a week without someone asking me where I have it done. Roger has also persuaded me of the importance of a more structured cut and of not doing the whole Anna Wintour thing and having a signature look, but changing it with the seasons. See my cousin's guest post on the matter of changing one's hairstyle.
It costs an absolute fortune and I must buy fewer clothes, but you wear your hair 24/7 and you can't say that of a dress.
