I'm MTF and pass with zero problems. That being said, I can go out in guy drag, turn on the awkward clomping about, put the 1000 mile stare on, dial the monotone guy voice down and presto, I'm a skinny guy and no one would even question it. Just as I'm able to do the opposite and achieve the opposite goal. People see what you show them and they know what you want them to know. I suspect much of that is because most people simply don't care. If you want to know if you pass either way, get around a pack of children. They're brutal! lol
