How can you tell if a woman is transsexual?

There is no sure way to tell if someone is transsexual simply by looking at them. Trans people come in all shapes, sizes, and appearances, and there is no one "transgender" look. Additionally, it is important to remember that not all trans people identify as male or female, so gender cannot always be determined by physical appearance.

If you are interested in learning more about someone's gender identity, the best thing to do is to ask them directly. This is the only way to be sure of someone's gender identity, and it also shows that you respect their identity.
