I have this specific T-shirt with the sleeves cut off. Something about it just makes it the perfect thing to wear on a masculine day (I'm demifluid. I shift between feeling like a guy or a girl with nonbinary being my static gender). I have other shirts with the sleeves cut off, but this one specific shirt, for reasons unknown, makes me feel the best.
I also like it when I'm out in public on a masculine day or when I’m crossdressing as a guy or when I’m dressed nonbinary enough that a store/restaurant employee doesn't know how to refer to me. They aren't sure if I'm a guy, a masc lesbian, trans, an enby, or whatever else they might read me as and they don't know what to say in regards to ma'am or sir. I feel a slight bit bad for getting enjoyment out of that because they probably just don't want to offend me or make a mistake that a few people would get a manager involved for. It's just the look on their face while they are trying to figure out which to use. Lol. And it's fun to see which one they will call me. It varies. I can go to one place and they think I'm a guy, I can go to another on the same day and they read me as a girl, and someone else might really not know how to refer to me which I get enjoyment out of. Lol… it's amusing to me.
It's equally great when I'm having a masculine day or crossdressing as a guy in public and people read me as a guy because that means I’m passing well enough. But then maybe I talk, and the other person will very quickly apologize to me. Lol. Sometimes I’ll laugh, but I mostly just tell them it's all good or don’t worry about it. :)
