Princess Diana's black taffeta ballgown has been sold to a museum for £192,000.

Hours after she wore that dress in 1981, you could buy a copy in London department stores. So when I was invited to a ball at short notice, I jumped into a cab on my lunchbreak and headed for Oxford Street to buy one of my own. It cost about £80, which was cheaper than Lady Di's but quite a lot of money for me at the time.

And it's still hanging in my wardrobe.

I couldn't bring myself to throw it out. Was I ever as slim as that?

On the other hand, if you have £192,000 to spare ... I'm open to offers.
