Victor Edelstein, the former fashion designer of Diana, Princess of Wales, has sold his modern one-bedroom flat in Bloomsbury for £250,000 and is buying a £225,000 studio flat in Knightsbridge. The second-floor Victorian conversion is conveniently near Sloane Square. "My wife Annamaria and I spend most of our time in Italy and Spain," he explains. "So we wanted to buy somewhere safe and central that we could just lock up and forget when we weren't living there."
