This is a great reproduction. Serious attention to detail. Quality materials and good craftsmanship. I ordered a size 50L and I am happy with the sizing. If you have longer arms (like sleeve size 36/37), I would recommend the size long, it is a great fit. The cinching strings at the waist and bottom seem long, but I prefer this over them being too short. You can always trim them if you want to.
