My Liberty bodice didn’t have buttons. It was a flannel vest with strips of a sort of twill material either side of the neck opening running down to the hem. It was a rite of passage, I think, when you were firstly allowed to stop wearing a Liberty bodice, and a further step to adulthood. when you discarded the Chilprufe vest, and didn’t even have to wear it in the winter!
We wore three gored worsted pinafore dresses - with a square bib and crossed straps. They had to be bought from the school tailor and as you were waistless at 11, and the skirt virtually reached to the ankles, it nearly saw you through to the sixth form having taken off the bib with the straps that restricted the budding bosom!
