It would be unfair to label every poor person or family as a chav. There are some people who just have a chav way whether it is a union jack t-shirt and pit-bull or leggings and high heels, not altogether because that would be just weird!! When I was small I remember an 'aunt' being labelled 'common as muck' by my mother who she described as 'brassy blonde, all tight skirts and red lipstick and nails' it must have been in the early 60s but to me as a child I saw her as 'colourful' and fun to know. I am sure that she must have been what would now be regarded as chavvy. Years later working in the city in the 80s-90s the word chav wasn't yet used as such but 'Sharons and Tracies' had that kind of a reputation, I am not sure what is current at the moment but the choice of children's names can be an indication.
