Clothes (and hair) do not make the man

On our holiday trip, I was mistaken for a guy at the marketplace of a smallish town. I was wearing shorts and a T-shirt at the time, and the person who thought I was male, was a woman of 50-60 years.

OK, so I've got a mohawk now... and my clothes aren't very girly (black, brown, shades of green but never pink or pastel), but how can a person not see me for what I am, with a T-shirt (under which I'm a C-cup)?

Another mistake almost happened during that same trip, this time the other person was a man of... I dunno, well over 60 anyway. He said something like: "And this... oh, is it a girl?" to which my father said, "Yes, she's my older daughter."

Daddy dearest still couldn't refer to my wife as "wife", though; it was *pause* "...friend."
