I went to a private Catholic high school where we wore uniforms: grey wool trousers and a navy wool blazer. My freshman year (1970) was the first year they allowed any color shirt and tie. I couldn't stand the feel of polyester shirts (I still can't) so my mom would buy me "traditional" cotton shirts. My friends that went to the local public school had a wider variety of clothing to choose from but I don't remember anyone dressing like those pictures!Too bad the majority of 1970s clothing consisted of cheap and useless synthetic costumey garbage. There were many nice clothes to be worn in the 1970s; I think it was the last time that wool was cheaper than polyester!
