Slack tide, chest seems a bit big if you wear a 36 suit. You may want to get someone else to verify your measure of 38" since moving your arms to measure can change the shape of your chest. Also, your ARM measurement seems short, buy it looks like Charly took care of that for you.
I thought that seemed short...especially if he wants stacking
My bomber sleeves are 27.8" and I can't imagine sleeves 5.5" shorter unless on a much much smaller jacket
I'm 5' 11.5" though I do have long limbs
Been considering if I should get longer sleeves got my 4 zip mdr...Charly suggested 26" and I changed it to 26.6"
