Until sometime in the 60s many Americans wore hats, both men and women. It was rude for men to go to church in less than a coat and tie, and suits in general were very common. In fact, that awful high school had a dress code until the end of my freshman year. One day I forgot my tie and they told me I could sit in the chapel study hall all day and take a zero for the day in each class, or I could walk home and get a tie. What morons! The women were all required to wear dresses and skirts with a minimum length and all that garbage. That all came to an end when the school refused to allow some seniors to take their final exams because their hair was too long. The result was a sit-in in the gymnasium (my very first political protest!), a lawsuit, and the end of the hated dress codes.
