Sloanes aren't cafe society or NYLON hedge-funders with million-pound bonuses, or London Eurotrash wearing upgraded style anglais. Ann Barr's and my original picture of them in 'The Official Sloane Ranger Handbook,' published in 1982, was of an upper-middle-class world, conservative and fairly homogeneous, united by old attitudes and institutions.

In London - and forget those extra public pressures on politicians - the lovely old Sloane world of manor houses simply hasn't cut it since Big Bang in 1986, the point at which Mrs. Thatcher really started to achieve her ambition to make this country more like America - its ambition, economy, it's very tangible measures of success.

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

Girls like Diana Spencer, armed with nothing more than a guinea-pig-rearing certificate, proud to say in that old Sloane way that she was 'as thick as two short planks,' became the exception as girls from Benenden and Downe House started to fast-track towards the City and law, consultancy, media and the arts.

Socially smart people have always mocked the threateningly mobile, and anti-branding is a central strand of high-end status conflict now.

Nobody knows anything. I deal with people in all walks of life, some of whom should have some idea of what they're doing. And they're all clueless. It's astonishing that any bridges stay up, or that planes don't constantly plummet from the sky. It's heartening, in a strange way.

Men turn to formal wear when they want a new job or when they think their current one is in danger. They try to present themselves as powerful and successful.
