What I meant by my last sentence “Especially when one grows up in a society/ is born in an era where putting on a hat may make them feel less yirah than not wearing one” was that for a person who grew up in a “modern orthodox” society but is yeshiva educated and frum, wearing a hat may not elicit the response/ emotions it would from someone who grew up in black hat community… it may be counterproductive. To demonstrate albeit through a bit of an exaggeration, someone from our culture wearing a kilt, although the formal wear of the irish, will probably cause more kalus rosh than it will add to someone’s decorum. If it’s not an accessory you are used to, the strangeness of the item may prove to be a distraction.
And just for the record, many very frum, very orthodox rabbeim do not wear black hats. Personally I have an extra level of respect for those rabbeim i know who dont feel the need to put on a black hat when they themselves did not grow up with one because they live the ideal that chitzonius is sheker.

I’m not really sure what your point was that you say you’ve made so well, I’d be interested if you would please elaborate… but to address your question about what I believe is respectable clothing?
A nice pair of slacks and a button down shirt are considered classy by everybody. Your identifiable as a Jew because your are dressed nicely and have your kipa on.
Just remember, they didnt wear white shirts, black suits, and black hats in the desert. That means that what has become the accepted norm was at one point a “new thing”. In fact, as other posters mentioned above, it actually developed in order to reflect the current period’s culture and accepted norms of dress. Adjusting what we consider to be chashuv dress would just be following that precedent
