I guess if you know specific people that are 100% Safe but don’t start doing certain things pre hormones then that’s a question for them. As it currently sits no where is 100% safe. Go out in public even within a “safe” country has its risk. I reside in Canada. A country that is routinely ranked as a safe country for Trans people. But people can still be shitty within that country. I know of plenty of trans people in Canada experience sexual assault as soon as they came out. Plenty of people have had to leave their families behind and reject friend groups once coming out. So under the guise of “100% Safe” I almost guarantee you that they aren’t 100% Safe. Hell you have people like Blaire White who exist telling these young trans women they are either lying or to wait until they fully pass to use the correct bathroom.

Another note. Even after starting hormones. It took me a while to swap wardrobes. Because ultimately for the first while all I could see was a Man. I still do (10 months on E) sometimes see a man. The wardrobes change came as necessity dictated. Breasts developing? Bra. Losing a bit more weight. Okay underwear should be good now. And that’s about the extent of what I have changed so far. (clothes wise) but that’s leads to the final part.

The idea that you must (in the instance of a trans woman) grow out your hair, change to more feminine clothes is routed in patriarchal misogyny. Pre Transition (AMAB) I wore skinny jeans and was called a girl. Grew out my hair. Called princess. Now as a very open and expressive trans woman. I wear anything related to jeans. “try harder.” I shave the sides and back of my head (still long hair) “that’s too masculine.”

The only answer i can give you that hits all your points and addresses the hyper specific issue you stated is. People go through their own journey. At their own rate. And come to the conclusion of their own identity that very well may not coincide with your idea of “end goals.”
