LOL.  My elder daughter used to waffle about her 'carbon footprint' - while taking about four foreign holidays a year.

Electric cars also much in evidence around my way. In case you miss the signals the cars are distinguished by having a green tab at the end of the car number plate. During the weekly rubbish collection, the 'green' car owners tend to be the ones with the most disposable rubbish.

AFS - Perhaps increasing affluence has actually diminished any sense of pride the individual had in looking 'sharp' or - at the very least - 'considered'.

100% correct. That and changing social conditions, remember the Sheffield steelworkers who used to dress like country gentlemen in their tweeds to take their wife out at the weekend? A brief escape from the hellish circumstances of their working lives. The 60s mods had no expectation of progressing beyond their parents circumstances other than to be something special in the evenings and weekends. Then came home ownership ‘for all’, well some of us anyway, you bought your house, started a mortgage and by the time you retired you had paid for it - bingo sitting pretty. Well that was the theory, except that somewhere along the way it also became necessary to drive a German car, have a German Giant vibrator, a Swiss watch, go to Oz on holiday, a 150??  television, shop in Waitrose,  build an extension etc etc. (none of which I give a shit about) Also somewhere along the way dressing to impress fell by the wayside. There’s no need to if you spend all your time immersed in the home entertainment hub. Someone we know is having a games room built at the bottom of his garden. I don’t think this is for playing billiards, shove ha’penny or cribbage, it’s more to do with curved screens, surround sound and flashing lights. I can’t think of anything worse. It’s costing him thousands and thousands, but then he is a plumber.

I don't believe the notion of 'affluence' should be confused or conflated with some unthinking sense of suburban smugness and complacency.  Some years back, when I still ran a business, one or two of the people who worked with me reported being directed to the back door by clients - often people from a working class background who were now revelling in living in detached houses with gates, intercom systems and several cars in the driveway.  Genuinely middle and upper class people could be totally different, often providing good coffee and sometimes food - and often gifts at Christmas and so on. 
My own brother-in-law grew up in poverty and now divides his time between Calgary and California.  Likes people to know how nicely he's done.

Rock certainly acquired a bit of a reputation as a Sloane paradise, didn't it, simply teeming with the kind of twits Strachan and Lally hated dealing with in Richmond.  I'd guess they chose carefully the places where Johnny Foreigner might be encountered en masse with a certain degree of sniggering care. 
Norfolk - or parts of it - are perhaps a bit like Rock.  I know my present wife, brought up poor, felt very out of place in one of the market towns we visited.  I'm a touch less class conscious than she is perhaps - but I've come across some grade-A imbeciles in my time.  'Supercilious' is sometimes the word used.  It fits.

I think in the current climate dressing Ivy looks considered. You're interested in a style as opposed to what's fashionable.

It also takes a lot of effort. The time spent tracking things down - either at full price or on Ebay, the exchange rate is against us and a number of brands have changed direction so that they're not relevant to us.

Contrary to this I've noticed that there are increasingly odd single items that fit within the Ivy aesthetic from brands that either have little to do with Ivy or have moved on from Ivy. These fall into the "buy before they disappear" category.

J crew are doing a seersucker pop over with LL and third collar button

Lands End have seersucker shirt with a  superb roll, LL and third collar button

Levis Vintage have reintroduced Sta-Press

Batucuda have a patch madras Harrington.Sounds wrong but it's oh so right

Ralph USA is working with Rancourt

Crocketts have got bucks this season

Uniqlo have madras pop overs

After the description of the Crockett & Jones bucks they add ‘This stand-alone ‘Ivy League’ style adds some American inspiration to this year’s Spring / Summer collection.’

They look like the quintessential dirty bucks Alvey, really nice but £450 is an ouch factor for me!

Those bucks look great.

I've got a Baracuta G9 in a yellow/blue/white plaid. As Woof says, it looks good with plain stuff, but only comes out a few days a year.

Robbie, I find the same with Uniqlo

There isn't one close by, so I always drop in when I come accross it. Never bought anything. Even by my standards either the detail or quality isn't quite there.

Last time I was in they had some really good khakis, in 34'' leg only.

I'll second Alvey's recommendation on the LL seersucker shirt.

I'd have to see Levi's sta press in the flesh. They've brought them back intermittently over the years in some very strange guises

Dickies reminded me of Sta-Prest: 'constructed' as the chap in the local 'vintage' emporium said.  I unwisely bought a pair around 2006 and did not get on with them at all.  In fact, a pair of USA-made L.L.Bean chinos I bought a month or two ago remind me of them: not likely to soften and crumple for quite a while is my guess.  They're so unlike cotton Silvermans' it's quite uncanny.  Poly/cotton often seems to make all the difference.  On the plus side, I can wear them when dealing with my five-year old grandson and his mothers dopy labrador.
