I used to present very feminine at work. Long hair, earrings, makeup, etc. Then I cut my hair and started wearing men's clothes including tee shirts under my shirts, belts, men's shoes, etc. Nobody said a word. TBH I did cut my hair in several stages, first to shoulder length, then a bit shorter, before finally going short. Nobody said anything. I also had stopped with the makeup and jewelry.
When I finally came out, I told the manager I thought it was obvious and she said no, they just thought I was dressing more comfortably. Shrug.
It turned out to be a non-issue, but yeah, nobody said anything at all. And then during that time they hired 2 new people who happened to be lesbians who didn't know my history (and I was not yet out at work) and both of them were all over me. But I'm a gay man and they couldn't figure out why a straight woman was so butch! LOL
