I have a maroon Harrington. It gets more use than the pensioner beige one. I also have a red one.

I wore the beige Keydge Ivy jacket during the hot weather. Safari jacket also got some wear.

I wore them: Baracuta, McGregor Drizzler and Anti-Freeze, London Fog.  Just after Christmas I bought a USA-made all-cotton King Louie in 'natural' (beige-ish - fawn?)  I wore it out once with Levis and penny loafers and decided it was a look I could no longer pull off.  Too much time had gone by.  I'd also become addicted to raincoats: Burberrys', Brooks, Aquascutum and other, slightly 'toffier' outerwear. 
To be frank, even years ago, I often struggled with zips.  And I was forgetting the ownership of Peters and Catalina circa 2009.  Same damn problem, even though they did not quite have the look of a Harrington. 
Chap in the local 'vintage' shop told me Baracuta own the name 'Harrington'.  Is this the case?

I've four or five Baracuta's and a JS Grenfell in various colours and cloths. Rarely wear any of them now. Wore the JS version when I met with Woof in London recently, first outing for it in about four years and it stayed in the hotel room for the rest of the trip, mind you, the weather was superb that weekend.

How to keep the appearance of 'affluence' quiet and relatively modest. 
Years ago I knew people who wore Barbour jackets (man and wife) with the little metal badges on, so that anyone in doubt could peer closely and say 'My goodness, that's a Barbour you're wearing, you must be affluent/good-looking/capable of shagging your wife five times a night/passing your exams without revising/whatever...' Knowing nods, winks and chuckles all round. 
I had a Grenfell jacket (not waxed) and removed the little cloth tag with a razor blade. 
I now favour a battered 'Bronte', padded inside (thickly) and the colour of a heap of dog mess. 
No badge, no logo, no affiliations, nothing.  A passing goatherd might take note. 
North Face was always dubious.  Even more so now.
Puffer jackets.  Doesn't Putin wear one? 
Bollocks to Barbour, though.  It's moved well down market.

I would suggest, too, that the Harrington jacket, like the button-down, the polo shirt, chinos and any number of Ivy/Prep/Trad items has been absorbed into the mainstream to such an extent the significance has been entirely obscured.
I was stood in line behind a guy - around my own age - last week.  He was wearing some kind of knitted garment, khaki shorts, no socks, deck shoes.  Superficially, he looked okay.  Looking closer, he didn't, he looked like a man of my own age who hadn't given a huge amount of thought to the way he looked.
There are not many days when I'll fail to see some fat chappie wearing a black (always black) Harrington-style jacket, often with cheap jeans and plastic-looking trainers.
There have to be alternatives.

God will really be up to no good when He begins dressing up old geezers (and young geezers) in seersucker jackets, white bucks, navy knitted ties, 'Guaranteed-To-Bleed Madras', cordovan wingtips and embroidered velvet slippers as referenced by one R.Press.

I put metal badges on my Keydge jacket. Not the maker’s name - beer and football related.

I am after a Wetherspoons metal badge.

Wore my beige Harrington, bought in Covent garden late 80s, for my daily pub visit. Bloke wearing Black Harrington on the next table. He was in a different league to me.
I looked affluent.
