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.
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.
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.
