Six inches bigger than 40 but a double breasted should fit a bit roomier in a late 80s/early 90s way.
I'm fond of DAKS clothing and have a suit very similar to @donkeyjacket2 's coat (nice buy his, btw).
I think it's more recent, but still a good one, labeled an UK 40 with 34" (double pleated) waist trousers and the only alteration I had made is lenghtening strides to the max, while slimming the hem at 21 centimeters. Jacked was slightly wider than needed but I simply moved the buttons outward of about 1,5 cm and called it done.
Pit to pit is 55 cm (about 21" 3/8) which fits well my 187 cm. x 83 kg frame.
The pit to pit measurement should be as worn, not with the jacket open, so DB and SB shouldn't matter. Measuring across the back would probably give an easier measure.
I have a SB DAKS flannel suit which I bought last year. I don't know how old it is but it is quite generously cut. That might put it in the 80s or 90s but it has more shape than you sometimes get from back then.
Thanks Guys, think ill just move the the buttons back a bit if its a bit big.Yeah, this. If the person measuring knows what they are doing, they will have buttoned the jacket as-worn and placed it flat before measuring. Sizing being equal, even a straight jacket measured pit-to-pit should produce the same measurement as a single breasted one
Nice cap like the check, goes well with the scarf. I have quite a few caps, my favorite ones are my gamekeeper tweed ones i got from rydale, made in england teflon coated for 17 quid, cant argue at that price.DAKS have an interesting history. I believe they were the first company to produce ‘self-supporting’ trousers.
I particularly like their house check and have a cap (which has a brief history of DAKS woven into the lining) and scarf in the check.View attachment 1536929
