This is a vintage 1985 gray and black herringbone custom-tailored men's partially lined wool blazer by Sears that has no size tag but measures about a size 46 regular.
It measures about 24" from underarm to underarm, 23" from the top of the shoulder to the sleeve opening, and 28" from the back of the neck to the bottom hem when laid flat.
The blazer is in good pre-owned condition with some discoloration on the lining.
