Frequently, people ask for advice related to being out in public en femme. This is a very broad (no pun intended) subject.

When I was relatively new to being in public en femme, I found that it was helpful to think that I would be playing/acting the role of a woman. This meant that I would take care to apply my makeup properly, select clothes, shoes, jewelry, etc. that were appropriate for what I planned to do and where I was going. Also, like any actress, I studied and practiced moving, speaking, gesturing like women that I admired. The more that I did these things, the easier they became. Thus, I no longer need to think about how should I act, etc. when en femme.

It is not reasonable to think that one can just get "dressed up" and everything will be fine. Like any other skill, practice before performance is
needed.
