Brands are useful ways of short-handing practically anything - look at the way Tom Wolfe first used brand name lists to sharpen up a character and a situation. Look at the most brand-referenced novel, Bret Easton Ellis's 'Glamorama.

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.

All brands, whether high-ticket luxury ones such as Cartier or Rolls-Royce or 'masstige' ones with luxe-y overtones but altogether more affordable, all want to grow. Even brands that may have started in a modestly niche design and lifestyle fashion can find themselves under pressure to go global or to sell out at the top.

Imagine a State occasion where the Queen is wearing trainers with her tiara because she thinks it will make people like her better, more folksy. It's unthinkable.
