It's easy to class a man as a transvestite if you see him wearing a skirt type garment (Scots excepted), but about a woman wearing trousers or jeans?
If you look back in time, for several hundred years, in Britain (and probably most of the western world) women wore dresses/skirts while men wore trousers or some form of attire that covered individual legs. I read somewhere that a woman was stoned in the street for wearing trousers in the 1890s. It was only during World War I when men were away fighting and women had to take on the men's jobs in factories etc that some women wore overalls with legs or wore trousers for practical reasons. The same occurred during WWII. Up to the mid 1960s, it was rare to see women wearing anything other than skirted clothing, especially at work or social occasions. Most women did housework, gardening, shopping in a dress or skirt.
About 35 years ago women started demanding equal rights with men and sex discrimination laws started to be passed. About this time many women started to wear jeans/trousers and recent court cases have ruled on the side of females wishing to wear trousers at work and school. We now have the situation where it's acceptable in society for women to wear "men's" clothing, but not for men to wear "women's" clothing. This makes it much more difficult to classify a woman than a man as a transvestite, so it appears there are more male than female transvestites.
With the increase of thrush in women and falling sperm counts in men both being put down to tighter clothing around the genital area, it would have been better if the sexual equality movements had brought about a change that dictated that the norm was for both sexes to wear skirt type garments.
I was born just after WWII and wore skirts and dresses untill my late teens when I tried a pair of jeans. I'd never been so uncomfortable in my life, and apart from a loose fitting pair of overalls for certain jobs, since then have never worn trousres again. I don't understand why anyone would ever want to wear trousers. After a persistant thrush infection in my mid 30s, I stopped wearing
knickers altogether - since then no more thrush. I feel much more comfortable in the hot weather, and winter's taken care of by long coats and skirts that come down well below my long boots,
