Trans people goes the through process of transition - moving from living as their gender assigned at birth to their gender identity.
Transitioning depends on the person and their gender identity. For drag queens and kings, transitioning means taking on the differences between men and women including mannerisms, voice, movement, and clothing. For transexuals, transitioning means all those things as well as changing their name and legal gender. For some transexuals, it will include hormones and surgery. Some cross dressers do not transition per se because they may just throw on a dress and be done with it while convincing cross dressers will learn a lot. Transitioning for genderqueer people consists of picking and choosing any gender elements they wish. Every person outside the closet goes through the process of coming out to people.
