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.

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.

By the late Nineties, we had become a more visual nation. Big-money taste moved to global standards - new architecture, design and show-off contemporary art.
