Fashion design is a good example.
Just save those ties you were wearing 30 years ago and you will be right in fashion today. I suppose that is one reason I hate to jump on the wagon when it comes to trying new things. Change just for the sake of change isn't necessarily good. That is where I mark the beginning of the radical movements from wild dress, verbal assaults, and protesting the Vietnam War. Anything that had been considered wrong was now right and vise versa.
