I've been able to get away with shaved legs, shaved arms, eyebrow shaping, wearing a women's watch, wearing women's shorts (not short shorts, just athletic shorts that are tighter than male shorts,) growing my hair out past "normal" male length, and women's jeans. And while there were people who noticed my eyebrows, it was all positive compliments on how good they looked. Shockingly, the thing that most commonly gets noticed out of all of these is my women's watch. SO many people ask me "is that a women's watch?" at my poker tables, but not a single one of them seems to notice anything else. People have also noticed my hair, but they just ask me if I'm growing it out, I say yes, and that's it.
Only one person has noticed my shaved legs, at least enough to say something about them, not a single person has noticed my arms, and not a single person has noticed my androgynous clothing.
In terms of HRT, when I ask my roommate if she sees anything different, her most common response is that "you look smoother." Which she explains means both in shape and texture. Nobody else has even noticed it, though, even though I have been posting picture updates every 4 weeks or so on my Facebook profile, along with a few subtle hints that something more than weight loss is going on.
You can get away with a LOT without being noticed. The closest that I've ever been to someone actually thinking something was going on with me, was when I got hit on by a gay guy at work because he thought I was, with the way I moved and talked and dressed and looked.
