dont thikthe article was as bad as some comments suggest but i do think there are some problems.

Most of all though, it's the note of "no discernible background" that hangs in the air, engulfing what's around it. What does that mean? That their ethnic ambiguity allows them to wear what they please?

what does ethnicity have to do with it? the stereotypical representation of the working-class (male) brit is most definitely white. ethnic minorities are disproportiantely poor, but class and ethnicity cross-cut each other too much to even get close to saying that they're one and the same.

the "no discernible background" (presumably) refers to the fact that whilst sportswear was massively associated with the working-class (and primarily male) youth - particularly in the mid-2000s when horribly classist idea of 'the chav' reached its peak - the trend for more middle class kids to wear nostalgia-infused sportswear has the potential at least to help erode the extent to which that particular style is bound up with class implications and subsequent character judgements.

the writer sort of highlights that here...

These guys not only enjoy buying fashionable, high-end brands, but they also—no, seriously, get this—enjoying wearing sportswear. And not fancy sportswear. They like wearing the sportswear of poor people, the kind they've been demonizing for decades.

...but then jumps to lazy conclusion that this appropriation and that all appropriation is inherently bad. i mean, in my eyes at least, the re-appropriation of cheap sportswear is more about childhood nostalgia than anything else. most kids pretty much live in sportswear stuff up until the mid-teens.

also...

The class system that the British media—so dominated by stuffy, white bread, rolling hills and a fucking mansion rich boys—are saying doesn't exist anymore.

i've genuinely never heard anyone (outside of government) express that view at all because no matter what classy u identify as its bordering on absurd to even suggest that the class system doesnt exist anymore. and middle-class peopleand charicatures are very often the butt end of the joke (albiet without the demonisation).
