Most "fashion advice" is catered to either rich people looking to waste money, or midwesterners white collar workers trying to fit in at the office.
But if you go out in public, no one dresses like that. They're wearing a lot of canvas, denim and plaid, lots of face piercings and tattoos, hoodies and beanies. On the fancier end, you'll see oversized flannel jackers and dad sneakers. On older people it's a lot of carhartt and Patagonia.
Out in the suburbs younger people wear athleisure, and older people wear cargo shorts and t shirts.
But when you look at style guides it's like "your guide to chinos and blazers" but only the most obnoxious finance and tech bros wear that shit.
Where do you find style guides for normal people?
Normal people don't read style guides
Browse more Instagram and TikTok if you can handle it lol
If you can, walk around the closest metropolitan city and observe people's outfits
Go to places where people will try to dress nicer for. Bars, clubs, skate parks, art shows/events, street festivals, concerts, thrift stores, etc.
