Here is an interesting excerpt about Camilla, Diana, and other Sloane Rangers from an article at http://www.ohio.com/mld/beaconjournal/11332407.htm
Gloucestershire is a well-heeled corner of the English countryside, dotted with forests, abbeys and stately manors. Parker Bowles, whose grandfather was the third baron of Ashcombe, grew up on a country estate in Sussex in southern England. Rich and well-bred Britons traditionally have been brought up in the country, not the city, on land handed down from their ancestors. This type of English countrywoman values looking ``practical and tidy'' above all else, Higginson said. That's because she often has more important things on her mind than what's in Vogue this month: caring for her horses, gardening or taking her dogs for a walk. Such women are often great animal lovers, Higginson said: ``Their Labradors and their horses are up there with their husband and their children in their affections.'' Parker Bowles' style is really a grown-up version of the ``Sloaney pony,'' said Jess Andrews, fashion editor of Tatler, the British magazine dedicated to the lifestyle of the upper classes. The term refers to Sloane Square, the West London neighborhood where members of country society often move after graduating from a good university and before getting married and moving back to the country. The look, which was documented by the early 1980s publication of The Sloane Ranger Handbook, features corduroy trousers, polo shirts and blazers for men, and pearls, sweater sets and tweed skirts for women. Understatement, in both fashion and attitude, is key. It's a look that Diana, who was from a similarly aristocratic background, embraced before her marriage, but traded in for designer gowns from Milan and Paris. There's no direct comparison to Parker Bowles and her ilk in the United States. Growing up and growing older with money in America usually translates into a perfectly coiffed, well-toned and ultra-groomed appearance. Think of the older models in a Ralph Lauren ad. Even in Britain, Parker Bowles may be one of a thinning breed. The Sloaney pony look is on the wane. The younger crowd of London-living aristocratic women are, Andrews said, ``more trendy, with short skirts and slouchy boots and bangles and messy blond hair.'' Think of Kate Moss and friends in those Burberry ads.
