I was neither and never will be bothered by things like that. I suspect some of your question at least in the UK will depend on your age. I remember watching some program called something like "Adverts That Changed The World" which mentioned Levi and thier succesful campaing with the person in the Laundrette. Here is a short extract from the first web article I just found:

"Levi's began to manufacture jeans around the 1870s, and jeans were originally working men's clothing. During the 1950s people aged 13 - 19 became known as teenagers, prior to this people were all either children or adults. Jeans became popular clothes for teenagers because they were seen as a sign of rebellion against parents and authority.

The jeans wearing teenagers then grew up and become parents meaning that the next generation of youngsters saw older people wearing the jeans and refused to wear them. This forced jeans to become unfashionable through the early 80s.

In the mid 80s Levi's hired a highly successful advertising company (Bartle Bogle Hegarty) who with a series of adverts turned around the situation, resulting in the sales of Levi's jeans rising 20 fold."
