When I'd pick up my date, and she had obviously spent a lot of time on her appearance, it'd make me feel like a million bucks.
I fundamentally do not understand what reason everyone else should have to dress to please you compared to themselves. Seeing everyone else as props to fit your preferred aesthetic rather than people who's desires about their own appearances are more important than what you want them to look like just seems selfish to me.
But people will judge you by how you dress, and you will miss opportunities as a result, and you'll never know that this is happening.
As I mentioned earlier, people do react to me differently depending on how I dress. And I've known many people who align with your views on this, and they've all wondered why opportunity passed them by (or they realized they needed to change).
Can I ask: suppose you were charged with a crime. Your lawyer showed up in track shorts. Would you get another lawyer? I sure would.
It's not a bus.
