Just to offer a slightly different opinion.
All I have to go by is your photo. I don't know what your voice, mannerisms, posture, etc, etc...
You are beautiful, you know you are. You are GOING to stand out. Men and women notice a beautiful woman and give a little closer look. And as has already been stated, none of us are 100%. See what I am getting at? I am a frumpy middle aged woman, the only people that notice that I am more than a human taking up space and breathing their air are dirty old men. That's not precisely true but it's close.
Honestly, I would take the tradeoff of occasionally being clocked, to be beautiful. This fear of being clocked is something we all have to get past if we are ever going to find peace. I have struggled with it so much. Just in the last couple weeks I have finally started to let it go. A really close friend who had started transition at almost the same time as me finally got gendered correctly. Wow, the look on her face. I had taken passing for granted and had forgotten what it was like to be misgendered.
None of that makes it easier to be clocked. In fact, it might feel worse to be clocked when it rarely happens. And it's not, hate to say fair cause fair and unfair have no bearing on how we feel, but... anyways, not fair that someone who should pass easily is outed because they are pretty and people pay more attention to them.
Just trying to add perspective. Something that, my friend being gendered properly finally gave me.
