Yeah - thx for your input so far. Unfortunately the seller is not overly responsive towards my questions
I’d assume that the yard stick is really floating and that the angle between the starting and end-point of the measurement will also account for a certain amount.
Eventually, 56,4 is just slightly above my comfort level. A 55 ist really snug when closed, but I like my jackets to fight right anyway at 190cm and 85kgs, it’s just about the perfect measures for that. A XL would be too roomy in the stomach and waist area unfortunately.
Appreciate all of your input so far

That’s the one I got - sure, some variation is to be expected and the yard stick is arguably not the optimal way. But both won’t account for the discrepancy

Hey all new to the forum here…
I just recently stumbled over one of these jackets on eBay and instantly fell in love. Especially since it has a good taper to fit my slim waist and hip
Luckily it was also my size (L). At least I thought so.
When I asked the seller to confirm the measurements of the jacket provided by IH, the P2P chest was about 6 cm off ( 50 cm compared to 56,4). Other measurements were about right.
Understandably I’m hesitant right now - wanted to ask for your experiences, anyone encountered the same?
Thx in advance
