Cheeringly, Sara Buys, who is Kate's step-sister-in law and something of a fashion guru herself, says she believes she is doing perfectly well with her "go it alone" policy. "There's absolutely no way that she needs a stylist, it's ridiculous for anyone to suggest it," Sara, the wife of Tom Parker Bowles, assures me at a party at The Club at the Ivy. "Kate is naturally a very stylish woman. She did so well in North America flying the flag for British fashion. She's made some great choices and I know designers are honoured when she wears their pieces."
