You're wrong. Style is subjective and it's abhorrent to suggest that fashion associated with certain races is inherently less tasteful than others. You should be ashamed of yourself.
On the second question, you make the mistake of framing it as a completely personal choice. But we are formed by our environment. I had no chance growing up in the 00s. Everyone had jeans and hoodies, maybe a sweater. I did not pay attention. I carried that into my 20s and only in my 30s have I started to care about my clothes and weight, which I regret so, so much I want to die almost.
I blame everyone. My parents are and where preppy but they made the mistake of thinking I would pick it up through osmosis somehow. But getting things handed to you or seeing, you dont learn tools, what things are called. I really have had to study and try on things, I remember I saw well dressed people in our capitol and HM models for inspo. 4chan fa board has helped a lot too but now overrun with zoomers but there are good threads.
I am too paranoid to post myself openly online, I have no instagram nor an active facebook so I will not post some imgur of myself here. But for work I tend to go with business casual chinos, OCBD and boots or loafers. You must understand, everyone is casual here and wears jeans at most.
Same with books and quality movies. It really is a struggle to find quality, but the internet does help. Like finding xfiles. Our state does upload good old movies to sort though the modern slop.
I'm not sure if that was intended as a dog whistle but you might want to consider that it's coming across as one.
