Thanks for pointing that out – I think there was a misunderstanding.
Just to clarify: my chest measurement (82cm) is full circumference, measured around the widest part of my chest.
My shoulder measurement (44cm) is across the back, seam to seam – not shoulder circumference. So it’s definitely not wider than my chest
Really appreciate all the insights so far. I’m learning a lot just from these discussions!

Thanks for clarifying. I understood you correctly.
Your chest measurement, measured in circumference, is 82cm (32.3 in), so you’d want a size 34 (JP) jacket. JP sizing is weird, such that their tag size is exactly their chest measurement and you’d want some room in your chest for movement.
Shoulder measurement (you said 44-45cm) is measured in half, from shoulder seam to shoulder seam. So to get a shoulder circumference, you’d want to double that, which is 88cm-90cm. That makes your shoulder measurement bigger than your chest measurement, if both are counted in circumference.
We, TFL members, often complain about Japanese leather jackets with tubular body but that’s pretty much what you want for your measurements. Same shoulder and chest measurements in a jacket give you a fitted shoulder and a bit of room for chest. If you get your jacket tapered by a tailor, you’d get a good fitted jacket. That’s a V shape from the shoulder to waist (not the typical V shape from chest to waist).
Let me give you an example of a typical sizing. I’m a size 38 chest, 31 waist. For leather jackets, the shoulder is 17” (43cm or 86cm if twice for circumference) and chest is 20” (51cm, or 102cm if twice for circumference). My chest is larger than my shoulder. Then I’d want a tapering hem to make my 31W (79cm) flattering. It’s like a diamond shape, if we are only looking at the body of the jacket.
