Going out and presenting is related to dress, mannerisms and confidence. That takes practice. Which means a lot of going out in the "cis" world to get that practice. When I was young I could wear and do whatever I wanted and passing was not an issue. The older I got, I started to wear things that were age and situation appropriate and that helps. But it comes back to confidence. For example, I had gone to a service last Saturday and was in a nice dress and heels and I went to Target on the way home. At first I was like, I don't usually wear this to Target. But today was a unique situation, it was a funeral service, so I shouldn't feel bad about it or out of place. I don't know if there were a lot of people looking, but I did have someone make an interesting comment to me when I was walking back to my car. They said "hey, beautiful". Which to me was a little derogatory but I was kind to the person. Anyways, you need to make eye contact and respond. Even if you do not have a "female" voice. Otherwise, the person does think you are strange, a little off or maybe lacking social graces instead of just being nervous.
