The whole passing thing can be a super sore subject for a lot of us.  When I started HRT and I was pretty convinced I would need AT LEAST a complete head transplant.  I was conivnced that this passing thing would most likely pass me up and I would always be misgendered...forever more.  That was several years ago now.
The first year was rough.  Noone could see me as anything but a "sir" or "dude".  Disheartening, but several of my sisters helped me to stay strong and hold to my course.  They promised things would change and I always thought, "that's sweet of you...but I know you are just being kind".
After that first year, something started to happen.  I was most certainly misgendered, but I began realizing that people were actually avoiding gendering me at all...like they could not tell, so they just left it alone.  I also started to get gendered correctly without any prompting or work on my part...so I knew something was up.  This continued on for about another 6 months and by 2nd transiversary, I was so rarely misgendered as to count it not happening.  It was a fair split of people gendering me correctly or not gendering at all.
About 6 months ago, almost all misgendering stopped, about 25% skipped gendering entirely and I was being correctly gendered 75% of the time...and I was amazed.  My routine is the same, a little eye makeup...but I still am stuck wearing a masculinizing uniform shirt and cap.  I figured it was just people being polite, but then I started to realize that these are strangers getting it right and they are not being prompted ahead of time.
HRT can do wonders and I realized that the effects just take a while.  I have gotten a fair share of "told you, patience is paying off!" from my friends who were urging perseverance.  For all of that, I still think I look like I did before, am still my own worst critic and still have plenty of self doubt to contend with...but I am doing it while being seen as the woman that I am
