Transitioning is a big change and there is a lot of uncertainty.
For myself, I started to wear androgynous clothing when I began to show changes in my body, but not enough changes to be gendered as my preferred identity. I never felt the need to suddenly start "dressing to the nines" to confirm my gender. I just sort of gradually eased into it.
Years ago, WPATH standards required a year of cross dressing to confirm some notion that if you don't like the current women's fashion, hair styles or make up, then you are not a candidate for gender surgery. What a crock! Thankfully, this is no longer a requirement.
Christine Jorgenson has stated that by those standards, she would have been denied gender surgery because she rarely cross dressed before transitioning.
My advice is to just do what you feel comfortable doing at the time. There is no need to force anything. Just be your honest self. Other people will pick up on your transition sooner or later and if they express concern, then you may gently let them know how you feel.
I wish you the best and take care.
