I shan't turn this into one of my fashion history lectures, but some here might like to google 'edwardian women photos'. The era covers the transition from tight-laced & boned stays to the roaring twenties. Thing is, we tend to caricature those women's bodies according to fashion plates of the time - but in real life, those women were too busy changing the world to fuck around being anxious about their weight.
I like checking my "normality meter" against these pictures, because photography was pretty common by then. It's very easy to see that even in the bones'n'bustles period, women weren't killing themselves to squeeze into the unnatural shape fashion wanted to impose. We just see a very diverse range of women, in rapidly evolving fashions, getting on with life.
And I am average. Average for our era, for Edwardian Britain, for my age - I'm only fat by an unnatural, unreasonable standard.
Looking at wartime photos and images from the '60s-'70s doesn't give a true normal. Wars bring fiercely restricted diet (people were so hungry, the government recipe book recommended toast sandwiches!) and the '60s brought amphetamines.
Mind you, it's very sad to see photos of poor Edwardian children :( They were emaciated.
