Nah it’s an interesting question. There could be many reasons why. You might just feel most comfortable when you’re dressed formally. My bro dresses formally all the time just because he’s a pretty formal person. The thing about women’s business attire is that it’s more conservative than most traditional women’s clothing because it covers up more skin and doesn’t try to play up womanly baby-making parts.* So you may find that it aligns better with your preferred gender presentation, or you might like the way it feels. I imagine it makes you feel powerful, because business attire traditionally asks for respect. And I’m sure people treat you differently when you’re in it. That could make a big difference for you if you feel like you’re lacking that respect in other parts of your life. So lots of factors going into it.
