In the context of gender, passing refers to a person's ability to be regarded at a glance to be either a cisgender man or a cisgender woman. Typically, passing involves a mixture of physical gender cues (for example, hair style or clothing) as well as certain behavioral attributes that tend to be culturally associated with a particular gender. Irrespective of a person's presentation, many experienced crossdressers assert that confidence is far more important for passing than the physical aspects of appearance. Groups of people whose members may be concerned with passing are crossdressers, drag queens and drag kings, trans men, trans women and those who identify as a third, non-binary, or genderqueer identity.
