Iffy topic. I'd been passing since my very first attempts at dressing/presenting female back in my early teen years.
No horomones, or hair removal, just clean shaven, and my makeup skills left.. LOTS to be desired.
(I will admit I was much younger and prettier then..) I just looked like an awkward bookwormish Wednesday Addams type goth girl wandering around.
Sometimes, even 9 months or more in, and after almost 2 years of hair removal, If I'm dressed like a slob, in super baggy, neutral clothes, I still get a 'sir' or whatever else, which comes to a screeching halt when I bark at someone.
The super baggy coveralls at work don't help either.. Especially considering, being as tall as I am, I *should* properly fit into a 40T however the inseams and sleeve length still leave much to be desired, and am forced into a 48T just to actually avoid a frontal wedgie and the flood pants look. (As well as having proper length sleeves.) I guess tall people, male or female, that wear coveralls still have little t-rex arms, and teeny tiny legs.
I'm still in the school that presentation, voice, and hair removal > horomones. Horomones only help my barely clothed image and to soften my face somewhat.
