I think you’ll have to provide some examples – ideally as photos – of streetwear fashion. Without any prior research, I only know the term to mean “comfy clothes” that would fall below the typical bar for “casual” dress code

A quick web search shows examples ranging from perfectly reasonable outfits consisting of normally-proportioned shorts, jackets, pants, and shoes. To some outlandish outfits that are prominently displaying designer brands.

And perhaps that’s the crux of the matter: what shows up on the fashion runway or “haute couture” magazines is never descriptive but prescriptive: a designer brand has a vested interest in getting the masses to believe that something is fashion so that they can move product.

Taken to the logical extreme, there is an idea that designer clothes is intentionally outlandish, precisely so that said clothes would never be worn by “normies” in day-to-day activities, and thus can always (and persistently) be projected as high-end.

Commercialized fashion is not a democratic experiment to see what most people want to wear. It is to move product every season. “Designer streetwear” is a poor approximation for what normal people wear when they just want to grab a sandwich from the bodega and then return to watch another episode from Season 2 of The Rehearsal. Maybe this should be called “real streetwear” to distinguish it from so-called designer goods.
