Hey Connie.
I feel that transition (which I understand as starting to live and present as my chosen gender and the expectancy of being treated as my chosen gender) would now still be premature. I don't have the confidence, the looks, the clothes, the... know-how yet.  It's just a matter of time now but it can't be rushed. Heck, I still wear male clothes even at home, the comfort of the habit.
Where I live, I won't be arrested. The worst thing that could happen is being asked to dress or leave. And the looks and talk behind my back. And ostracism. Anyway, since going out topless and in bra-piece is equally disturbing thought, the swimsuit is definitely the right and more progressive choice.
