We all agree there is a certain objective “classy style” that should be obtained by a ben torah, or jew in general for that matter. Not because any specific garment (other than tzitzis and kipa obviously) does the trick, but because we are supposed to hold ourselves in esteem.
Truth be told:
No one has said that a hat CAN NOT be considered kavod shabbos. What has been said is that it is not a requisite of kavod shabbos, or of being a frum shtark yid in general. It is an accessory, and an optional one at that.
And in a similar fashion to what I answered above, society by in large does not accept a pink sock with a pant leg tucked into it as formalwear, or as classy by any means. So while I appreciate the image you’ve conjured in my head, please try to read and understand the previous posts before you decide on a condescending retort.
