Don't really know what you're getting at with that PoC (although I'd like you to explain), but anyway, I agree that Brits are not at all aesthetically focussed, on the whole. We're definately influenced by the LA trash thing - except the bellies on display here tend to be rahter more substantial (if no less chemically brown)! There are "pockets of resistance", but they are, really, few and far between.
This would be my assesment of the current main movements in British notions of aesthetics:-
Vast Majority - chav/chavettes/chavlets (baby chavs) - you know the drill - gold chains, pink lippy, white shellsuits (tucked into sports socks), white running shoes, bra tops (but no bras), and burberry, burberry, burberry...
Followed by (although some degree of overlap with chavs) - mediocre high street style - girls wearing what sienna miller wore last year and guys wearing (a) white trainers (b) slightly flared washed out non-selveged jeans (d) cheap print tee shirt (usually red or pink or green, possibly with some kind of semi-offensive slogan directed at females so that females come up to them in bars to dicuss said slogans as a precursor to some kind of sexual activity) and either zip up top or cheap pinstripe blazer
Followed by - students (although some degree of overlap with mediocre high street style ("MHSS")) - almost the same as MHSS, but with converse trainers, and the occassional bit of more "high end" streetwear - Stussy etc.
Followed by - street stylee - (althogh, yep, same as before... ) vintage jeans, tsubi jeans, rogans, g-star etc, but always some kind of jeans, limited edition trainers, Nike, New Balance or Addidas, more abstract arty print tee shirt - by silas, tonite, bape, maybe even undercover
Followed by - rich b*tch/bloke designer - prada, gucci, loads of money, entirely no style
Followed by - London Trendy - shops in Browns, Koh Samui, Matches - marc jacobs, helmut lang, chloe, stella m, same amount of money as above, marginally more style
Followed by - the five or six indiviuals who are left, and not covered by the above, all of whom , I assume are members of tfs!
