This is an Amazing! Blazer. I have never come across a blazer with fabric like this.. It is a very high quality, dense, smooth wool cloth.. It has a sheen, with a smooth, non-porous weave. It gives the coat a lot of body and shape and weight. After some research, I believe that this is a tin cloth fabric.. or oil cloth.. That would be a wool that is treated.. but, The feel is not that of oil, it is clean and smooth. There is a name of a tailor inside,, so I think it is bespoke. One pocket is still sewn shut, and the coat is pristine,, I don't think this was ever worn or just not enough to show it.. It is a dark brown with a subtle red pin stripe. Fully lined with a thick lush satin lining. Two inside pockets and central back vent. Measurements: no size tag. Chest: 22" across, seam to seam . leave 2" and this should fit an actual 42" chest. waist 20.5" across hip" 21 across sleeve 25" from shoulder 17" shoulder to shoulder 29" length, down center back, from bottom collar quick shipping non-smoking thanks!
