Thanks for this! Yeah - the problem for me with this - and with most Japanese clothing - is that they fit small for their tagged size. That means I would have to look for at least a 58EU/48US...and unfortunately those sizes have proven to be extremely rare from Japanese brands.I am pretty standard US 42 (Eur 52) with 36 inch waist (sometimes closer to 37) and svelt 185 dad bod. Non-Amroury Ring Jacket Suits and Sportcoats fit me fine in size 54. they are slim, but nothing sizing up one won’t fix.
In truth I am usually drawn to Italian designs/styles (specifically Napoli) more anyways, and they are almost always much easier to find in my size.
