"The British Teddy Boy subculture is typified by young men wearing clothes that were partly inspired by the styles worn by dandies in the Edwardian period." - "It featured tapered trousers, long jackets and fancy waist coats." - "Teddy Boys made it acceptable for the first time in post-war Britain for young people to care intensely about what they looked like, and to dress for show, instead of having work or school clothes and Sunday-best." -

The thing I find most amusing about this style was that teenagers started dressing this way to SHOCK their parents.
