Seersucker I still like, although I haven't worn it in years.  I had a jacket, imported from the USA, I wore quite simply with L.L.Bean jeans and white bucks. 
The first time I set eyes on TRS he was wearing a seersucker jacket from Chiltern Street with a polo shirt, probably Levis and desert boots.  Standing outside 'Bar Italia' in my shabby Burberrys' and off-white Levis chinos...  we spotted one another from afar...  He is quite tall, our John, and looks good in his gear.
Better by far than I.

Back in a couple of weeks was the last news I heard.....I'm waiting patiently....ish

Err … monkey boots.

And not just any monkey boots! Fucking ugly looking ones at that.

Monkey boots?  Seriously?  I only remember them being worn by gum-chewing, deeply sexy, rather hard-faced girls hanging around in damp bus shelters, smoking Number Six.  Lads would have been laughed into oblivion.  You had to buy your DMs from the shop on the old Derby bus station.  Probably your clip-on braces, too.
My word.

Navy blue seersucker jackets are in stock in limited numbers, but don’t appear to have gone on line yet, so if you’re interested you’ll have to phone. I’m afraid I succumbed as the cut and fit was perfect for me.

Also tried on their full length cream colour raincoat, as modelled by ‘The Mumper’ on their FB page. I was most impressed with it, very stylish, but I need another raincoat like a hole in the head. If I were in the market for rainwear I would be very tempted, possibly more so by the vintage London Fog they have in which is in a subtle dark charcoal check (plaid) cloth, now that is something different.

Sid is right.  My Brooks unlined is a lovely-looking coat that is utterly useless in anything but a light April shower.  I wouldn't want to put many of the others to the test and rely on my Bronte waxed jacket for venturing out on seriously rainy days.

You guys miss the point. Raincoats are not meant to keep you dry. They are meant to make you look cool, worn with a rollneck, rolled up Levis and chunky Paraboot Michaels. French Ivy if you like. Must be seen sipping multiple espressi while so adorned. And must be 100% cotton and scrunched up looking. Polycotton gives you an old mannish vibe.

Interesting point from TRS, that.  Finding them in pure cotton is a bloody nightmare.  Take the most costly items you see and they're often shudderingly unnatural.  I'd like to know more about the '21' from that point of view. 
Poly/cotton is unsatisfying - as with this Russell Athletic sweat I'm wearing at this very moment.  Shirts made of poly/cotton I reject out of hand, even if 'Boom Years', and have noted some Brooks horrors for sale on Ebay: Dacron etc.

There's at least two remaining dry cleaners who offer that service I think - one in Tooting or similar, and one in North London somewhere. If you ask a regular cleaners about reproofing though, they assume you want a jacket re-waxed.

Bugger all to do with i-gent anguish or i-gent anything - merely a simple preference for natural fibres.
Thinking about it, though, a few pairs of USA-made trousers I own at the moment are poly/cotton, including a rather Sta-Prest-ish pair of L.L.Bean chinos.  They can be chucked in the machine, dried and put on again without losing their crease (if that's what floats your boat) - quite unlike Sllvermans' (cotton), which need a damn good pressing (unless one is doing the 'rumpled' look).

Maybe they've gone....but these are the north London people....https://connoisseurdrycleaners.co.uk/contact-us/

Ie heavier weight materials....but actually ignore me, I bet a tweed or corduroy would work well
