There are pop managers, and then there's Simon Cowell, who isn't gay, Jewish or particularly riveting. He's not without interest but he doesn't exactly have the hinterland of, say, Brian Epstein.

Imagine a State occasion where the Queen is wearing trainers with her tiara because she thinks it will make people like her better, more folksy. It's unthinkable. But that's patently the thought process Gordon Brown (or his spin doctor) went through before the Prime Minister appeared on the world stage in Beijing without his suit and tie.

If beauty isn't genius it usually signals at least a high level of animal cunning.

There was a time when formal clothes were one of life's great pleasures, as well as a way of describing instantly a man's status wealth. Toffs wore the most, the proles the least.

Prince William looks good in uniform and Man-at-Hackett black and white tie (he has grown up wearing it constantly); less certain in his suits, which sometimes look borderline archaic; and variable in casual.
