*I think vanity sizing complicates our view of what's normal now compared to back then.
I remember putting a bit of weight on and having to go up to a 14 in top shop in the early 80s. You were hard pushed to find a 14 and never a 16. So i was the LARGEST SIZE Top Shop sold for a while. Wow i felt a fatty. I dieted.
Photos of me back then show me as very very slim. A today's 8 -10.*
My mum was a size 18 in the early 1950s, she always had a bit of a complex about her size. I have photos of her in a swimsuit at that time and she'd be a size 12 these days. (If you make your own clothes, the sizes in the patterns are much closer to those sizes than today's sizing).
When I was a child in the 70s there were two of us at primary school who were chubby. And at secondary in the early 80s there was me who was a bit chubby and a girl two years younger who was obese.
Also in Primary there was one person in the whole school who had asthma, one girl in my class who had eczema, and that was it.
Everyone walked to school barring the ones who lived miles away. I go past the primary school I attended and now the road is filled with cars at chucking out time which I find ridiculous for the distances concerned.
I was a size 14/16 as a teenager and buying clothes was a nightmare because 16 was the absolute maximum you could buy outside specialist catalogues that had frumpy old lady styles, and the really high fashion shops stopped at 14, like the above poster says. I've never been able to buy anything from Top Shop, ever!
