My mother fluctuated between a size 10 and 12 until the menopause, when she put on weight that she never lost again. She had a 22 inch waist most of her life, I beat her by and inch when I was seventeen. One of my schoolfriends at that time had a 20 inch waist and a bosom that woke my envy!
In my childhood I remember and photos bear me out that while my paternal grandmother was quite slim, most ladies her age had what was called "a matronly figure". In other words, no waist to speak of if they were not wearing their corsets, which of course they usually were, and a prominent bosom.
Come to think of it, Grannie's slimness may have been mainly owing to her salmon pink boned corset that laced all the way down the front. I clearly remember seeing the garment on its way to the wash.
As far as I remember dress patterns were sold either in Junior miss, styles and sizes as opposed to ladies styles and sizes.
I remember one or two elderly ladies who were spoken of as stout - actually, they were fat, but there were not nearly as many large people as we see now.
I think a lot of the mature ladies of my childhood probably were fairly heavy women, they tended to dress in skirts and jackets or cardigans or in fitted dresses sewn in panels that did not overly emphasise their waistline.
The generations could be clearly recognised by their clothes, young women, my mother and her age group fwore brighter clothes and flared or gathered skirts, unless they had what was called a fuller figure, when they adopted the styles worn by their mothers and aunts, but not the colours.
Grandmothers and great aunts dressed in navy blue, grey, brown or black. Grannie had a very dashing navy blue straw hat that I clearly remember, and I have a vision of a black summer dress with tiny white polka dots, but try as I will I cannot see the face of the wearer.
My other grandmother was a widow of long standing and wore for preference a small pill-box hat with an eye-veil.
Other ladies of their age wore round felt hats, rather like our hated school ones, or the slightly more sightly felt hats sewn in triangular wedges that the district nurses and midwives adopted when they got tired of their felt pill-boxes.
I doubt clothes manufacturers are responsible for our weight, but certainly now when people are not restricted to dressing appropriately for an age group the merits and demerits of our figures are perhaps easier to spot.
