In 1957, left, the average-sized British woman was 5ft 2ins tall, weighed 9st 10lbs, had size 3 feet and was a dress size 12.
She had a petite figure, with a slim waist of 28 inches and 34B breasts. Miss Average was expected to live 73 years and earned just £10 a week.
But flash forward 60 years and the shape of the typical British woman has changed dramatically - most strikingly in her waist and breasts.
The 2017 version of Miss Average, right, is 5ft 5in, weighs 11st, wears a dress size 16 and has a shoe size of 6.
Her bust has shot up more than any other part of her anatomy to a more shapely 36DD and her waistline has increased by six inches to 34 inches.
