How can I pass as a guy (FtM)?

[Nicole]

First, a haircut. Unless you want to go with a long haired guy look, for which I would say your hair would probably look most masculine bound at the nape of your neck. And then of course the masculine clothing. Ace bandage over your chest to minimize your beasts if you're pre transition. If you're truly and surely a male inside, the behavior should come naturally, and the way you present yourself should tell people who you identify as, if there is any question. Hormone therapy helps too.
