Probably not, if they had no clue you were transitioning.
Usually, people mistake me for my brother.
I was best friends with this girl for 9 years and went to her house like every week.... well until 2 years ago... I went to her house for a party last week and her dad didn't even recognize me. Lol.
At work, I've run into teachers that I had in 2009 and they didn't recognize me either.
