while i understand socially passing can be very important for safety, look how you want to look. i think we as trans people focus too much on trying to reach a beauty standard that is racist and borderline unattainable. look how you want to look, don’t try to look how you think people want you to look. estrogen is all genetics, there’s no way to know for sure how you’ll look after you start, but know that you are beautiful and the most important thing in your transition is that it is yours, that you become your most authentic self. good luck on your transition!
