I was lucky in this regard.. I had all the same fears as the ladies here, my parents had already disowned me. I was very gender neutral in public, the only real hint of femininely was the studs I wore in my ears, my long hair and my shaved legs and all of these traits are acceptable for males as well.
Something happened in my life which kinda solved this for me.
Just after I started HRT, i moved to another town due to a business opportunity. So I on moving day, I got into the car as a male and got out on the other side as a female. We did travel over two days, so day 1, I wore a very gender neutral outfit, only underneath my female side was present, a panty and a sports bra, the sports bra helped protect my very sensitive nipples. The bra was not noticeable due to the hoodie I had on.
The second day, I wore a long winter dress, some hooped earrings and I even put nail polish on my finger nails. When we arrived I was girl, and all the people I have met in my new life, have no idea I was ever born a male.
