It might have been touched on but if not, it must also be noted that many people "out there" couldn't give a rat's arse about clothing and see the stuff in the spirit of function over form. They'd probably laugh their heads off if they knew what many around here spend and obsess about in terms of jackets, boots, jeans, etc. But I'd wager that many of those people would spend an exorbitant amount (proportionally of their income) on something in their lives be it sporting/leisure related, automotive, etc, etc. It's human nature to have an interest and a passion for something(s) and here, for many, it's vintage or vintage-inspired clothing. Just don't expect the vast majority of the public to be concerned about such things as well.
To use leather jackets as an example, most out there would be very happy with one bought from a mall, and would probably think that us here with all our handwringing about hide choice, linings, 1/2 an inch here, 1/2 an inch there, would think us a bunch of anally retentive muppets with too little to worry about
Different strokes for different folks, simple as that.
That's not really true in the UK to be honest - the lads in the UK, and the girls, have a keen eye for clothing and fashion. I'd actually be so bold as to say that apart from Japan, I think the UK has the best high street fashion, and fashion outlets, of any place in the developed world.
There's so many options for high street fashion that even the smallest town will have a raft of different shops, from Topman / River Island / Bank / Scotts for the men, and even more for women (which I don't keep track of, what with me being male).
Insofar as leather jackets are concerned, you can pick up a leather or suede jacket - bomber jackets / trucker jackets, for about £100 - £150, from the likes of Asos / Zara / Topman or H&M - these for example:
They're not top notch leathers (pig skin, I'd imagine), but the quality is pretty good for the price and for £100 you can't complain. Lots of leathers available as well - I've actually noticed a bit of a trend in UK high street stores as well when they've started dipping into better quality materials because there's bit a palpable shift in demand (so they're using wool to make jumpers instead if acrylic / make leather / suede jackets out of real hides and none of that PVC rubbish.
