A liberty bodice was like a vest but made out of a soft, warm fabric. My mum made me wear one during the winter when I was very young. I suppose in the days before central heating we needed all the warmth we could get.
When I think about it - this was my winter school gear when I was about 5 years old - pants and woolly tights, vest, liberty bodice, full length petticoat, school blouse and skirt then a cardigan! If I was going outside, then this ensemble was topped off with a school blazer and trench-coat! How on earth was I able to move???? Getting ready for PE (gym) must have been awful - although when I think about it we didn't have PE kit in primary school, we just pranced about in our uniform. No wonder! Teachers would have had to spend an entire morning waiting for the little girls to divest themselves of all their layers!
Discovered that liberty bodices (sometimes called "emancipation bodices") were introduced when flapper gals abandoned their corsets and freed themselves from the tyranny of restricting clothing. Although given what I had to wear when I was little, I'm not sure my Mum got the message!
