have a working relationship. She's the most extraordinary person to work for, obviously, otherwise I wouldn't have hung around. I get asked so many questions about Anna and it's so annoying – think of something else! I have a life, too, ask about me!
JJ: You wrote about Princess Diana visiting the offices of British Vogue for style advice after her wedding. Now that the Duchess of Cambridge is under the same scrutiny, what do you think of the choices she's making?
GC: I think she's getting it right. She's a very attractive girl and she never pushes it too far because she shouldn't and she probably wouldn't want to. She has to look pretty and I think she never makes blatant mistakes. Even if she wears the same dress five times, she does it very well – it always looks fresh when she puts it on. I think she looks gorgeous. I think she wears too many hats, but she's a marvellous person to have joined the royal family.
JJ: Of all the designers that you've worn, what have been the pieces that made you feel incredible?
GC: I was very passionate about

Saint Laurent when he was alive. The one piece I really regret giving away was a beautiful coat of his. It was green, mid-calf and had a little belt and very square '40s shoulders. I loved it and kept it for years. I also had an evening dress that Azzedine [Alaïa] gave me. It was floor-length with a tail and batwing sleeves. I felt amazing in it. They're the best pieces – the ones that hold a memory. Grace: A Memoir by Grace Coddington is out now
