An absolutely miniscule percentage of us ever pass, if by "pass" you mean being mistaken for a genetic female.
But there is a standard I aspire to which I refer to as passing in a crowd or passing at a distance. It would annoy me if people were reading me a hundred yards away or everybody stopped and stared at me. It would tell me that I hadn't put enough effort into my hair, makeup, wardrobe, or especially my walk.
I've learned that it's relatively easy to avoid that when going out dressed in the daytime simply by making a bit of effort. People are too busy wrapped up in their own worlds worrying about their own problems to notice, or even care, if the person over there in a dress is actually a genetic female.
Of course I won't fool anybody in a one-to-one interaction. But most such interactions are with shop assistants where my money is as good as anyone else's.
