What might you have worn to go to school in the 1950s? It is likely that you would have worn some kind of uniform, both in primary and secondary school. School uniforms were worn, in part, so that everyone dressed the same, no matter whether they were well off or not so well off.
Most boys wore short trousers, most girls wore frocks. The woollen jumpers and cardigans you wore were probably knitted at home by your mum.
