UK kilt jacket sizing!??????

[artificer]

... tailored to fit. I have a large chest/shoulders, but narrower waist (44 inch chest, 39 waist - but I wear 36 waisted slacks, go figure*).
...
* And yes, I measured without inhaling/sucking in my gut, and I do have a gut that I'm trying to get rid of. Is the garment industry automatically resizing by 3-4 inches, or do the trousers actually strech that much?

Yes, the garment industry varies WILDLY with some brands running nearly true to measure and some more than +4" greater than the given waist size.

Vanity sizing... Doncha love it?

It's best to try on jackets. I have kilt jackets labelled 46, 48, and 50 which are exactly the same size, fitting me just the same. They're from three different makers.

Likewise one maker's "Long" jackets might have the same sleeve length as another maker's "Regular".

I have two jackets, a 48L and a 48R, which have exactly the same sleeve length.
