My friends adore 'TOWIE' - the TV documentary series, 'The Only Way is Essex.' They like it, I'm afraid, for the most unworthy of reasons: class mockery. They tune in to wonder in a 'can you believe those people?' way at the natives of Brentwood and Buckhurst Hill.

Advertising has always been a huge unrecognised source of outdoor relief for the arts.

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.

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.

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.

Across the Atlantic, commercial therapy of all kinds provides so many more comfortable outlets for people when they are under pressure. The English tradition is to get a grip, whereas the American version is to get in touch with your feelings, to say: 'I'm a good person. Isn't it terrible when bad things happen to people like me?'

When I hear about something allegedly happening in the world I always ask: who is doing it? Trends break out because they're based on real demographics, like there being fewer nuclear families or more people living alone. If 10 people in Shoreditch are doing it, it's a 10-minute fad.
