Patriot-Wear
Patriotism for your country was something Americans felt too hard, but the youth had its way of thinking that set it apart. Hippies found themselves at odds with the government and its policies and stances. That is why a counter-culture developed that rejected the accepted norms of society. They refused to let people gate-keep what should be considered normal.
Some folks wore the American flag as clothing to make a roaring statement about their political views. Everyone had a unique way of expressing themselves. There are versions of the peace flag that people wore, which closely resemble the American flag but have peace symbols, not stars.
