At lunch today at the next table was a woman who looked remarkably like John Lithgow in "The World According to Garp," except perhaps a little shorter and a little broader. She had a fairly masculine face, was dressed in jeans and sweatshirt, and it wasn't too hard to imagine her playing at least semi-pro football. I assume she was a natal woman because:
1) the chances of running into another transwoman are slim,
2) her facial skin was smooth,
3) she carried herself as a woman of that size and dressed that way would,
4) she appeared completely comfortable with herself, and
5) she was with a man who looked of the same socio-economic class as she and who treated her like a partner.
While I was thinking about her, a woman of about 30 came in – slender, over 6 feet tall, long straight hair, nicely dressed, pretty in a rather exotic way. I assume she was a natal woman also. She was alone, but 1-4 apply.
There are many cues as to the sex/gender of the person we see. Some of them are external (size, shape, clothing, hair) but many are internal (carriage, behavior, mannerisms, attitude). I really think that you could dress up a 5' 6" small-boned man who has a pretty face and smooth skin, and if he acted like a man or was nervous in his presentation he would be clocked as a man.
The cues are subtle. As trans-people we pass a lot better when we just let ourselves
be the gender we are inside. (Sometimes easier said than done.
