I should have clarified in my previous post that I know as a society, we are more casual in how we appear and dress in public than we were 50+ years ago. I don't expect protesters to wear a coat and tie or dresses to get their message across. Sorry if I mislead anyone in that regard.
But one thing that hasn't changed is that one's appearance and apparel creates an impression on others. It is a factor in how others perceive you and how your message is received. It can also improve your self confidence. That was a point I was trying to make.
It's also one of the concepts in a program you may have heard of "Dress For Success"
