I wish to relate my childhood recollections, mainly regarding clothing. I attended the local infant school from age four to seven. This was in north-west England between 1966 and 1969. School starts in September, and my birthday is November, so I was one of the oldest kids in the class.
It was a mixed school, and all boys wore grey shorts; other than that, there were no uniform requirements. Most boys had grey shirts and a pullover in some pattern, or a plain colour. Most were grey. As far as I know, the girls could wear anything,but they all wore dresses or skirts. No girl ever wore trousers or shorts – it was unthinkable.
