I wore a rubber buttoned liberty bodice through the late 1940's. Stopped when I went to Secondary school. Also, remember that we wore very baggy navy knickers, and my Mum always insisted that I wore a pair of white ones underneath,. Those baggy knickers were great for tucking in our skirts so we could go tree climbing, turn upside down in the playground. Seem to remember that for PE we just stripped down to vests and those baggy navy pants.
One of my Uncles was a tailor and he made me what we call today a Trouser Suit to help to keep me warm during 1948. My Mum thought it would be a good idea for me to wear this to school, only girl there ever to wear trousers. Mind you, school was not all that warm, far too large, ancient Victorian building, and our only toilets were in blocks the other side of the playground to the school building. No heating at all in them.
