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.

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. But completely comfortable in the Sloane uniform of non-designer jeans and chocolate-brown suede loafers. He'll look fine in Boden.

By the 1980s, practically no one under 60 in the real civilian world wore hats for anything except weddings, funerals or Ascot. Hats had been in competition with hair, and hair had won. Thirty years before that, Brits of all classes and ages wore hats all the time.

The White Company offers its loyalists an altogether better, whiter world. The White people have edited out any colours that aren't white, off-white, milk chocolate, grey, taupe or black. They can't be doing with Johnnie Boden's cheery Sloane jokes, his spots and stripes, his occasional 'if it's me, it's U' loud colours.
