In Russia some years ago, it was quite cool to keep important things – keys, wallet, mobile phone, on the end of a long chain that hung down to your leg. You had to be young to do this. Not many of the followers of this realized that it came from Britain fifty years ago. In those days, that long chain was one component of the “Edwardian” style. It went together with a big jacket and very narrow trousers. The people who dressed like this were the “Teddy Boys”, the original youth culture, and, first of all, they were just youths who dressed in a particular style. In Britain, youth culture is much more than fashion. Put on the clothes, you start to move in a different way. If you don’t dress and move like other young men, then you make older and more respectable people nervous.
1. It was fashionable to keep your belongings at the end of a long chain in Russia some years ago.
