While working in the costume collection at the university, I noticed that 5 ft. 9-10 inches and about 170 pounds seems about average for the men. (Archie Butt was 5' 10'and 185 pounds in 1907, but he was very fit and muscular, and terribly athletic). The ladies seem to be about 5' 3-4" on average with dress sizes running on average with what we call today a 6 or 8.(about 120 pounds) There were of course exceptions to the average- very tall men, very wide ladies, extremely petite etc,- and tailors and dressmakers must have been very busy keeping up with all the work. It is hard to find really large and wearable clothing from the Victorian- Edwardian period- our bodies are so differently shaped. Girls began corseting young. Our waists and bosoms are allowed to spread all over the place (not to mention augmented).
I think the last restrained generation must have been my own back in the 50's when the gals still packed into nature-defying girdles and bullet-proof brassieres- and we never left home without our thighs clad modestly in Lycra-Spandex. The thing I notice most is how narrow the feet were for both men and women in 1912 and the ladies seem to have a size which today would be about a 6 or 7. Women's feet have gotten enormous today with the average size now at 8 1/2 with a great many gals going into 9-10 and even 11! Jackie Kennedy wore a size 10. Women's body shapes were quite different too, owing to that S-curve corset and mono-bosom look at the turn of the century. Posture has certainly changed as well-just take a look at how women carry themselves nowdays-in 1912 I suspect it would have been called "wanton abandon". Marjorie Newell had the best posture of anyone I ever met. She sat right on the end of her seat with a ramrod straight back at age 102. I complimented her upon that one day and she explained ladies were taught how to sit in the good old days. And how they could sit for hours without fiddling and figeting or having to go to the "convenience"- she said they all developed marvelous bladders as a consequence! Naturally anything connected with bodily functions was to be avoided.
Also of note is the difference in hand size. Gloves of the period are long, thin and narrow. Ladies never left the house without gloves, some slept in cotton gloves at night, after massaging the knuckles well with rose water and glycerin, and of course middleclass- to upperclass did not redden and spread their knuckles by doing housework which required soaking in hot water. The wearing of gloves helped delay brown spots, kept chapping and sunburn away and gently molded the hand. A soft white hand was the sure mark of a real lady of refinement. You may recall that in the film The Age of Innocence, May (Winona Ryder) had her hands sculpted in Paris- which was the rage for the wealthy.My great-aunts and granny had a horror of the full sun and never went out without a sunshade or large-brimmed hat-they were born in the 1890's and knew a thing or two about the devastating effects of the sun.
