Many tailors and some of their customers love (fine) vintage cloth, because it easier to shape with the iron than the modern tissue paper fabrics. In general tailors can deliver a bespoke suit, which drape more elegantly, if they use vintage cloth. The downside is the coarseness and the weight, which you must get used to.
Here’s me posing in a bespoke blue suit made up in Italy from a vintage multi-ply Red Tower type of fabric. It has the famous and to some infamous shirt sleeve shoulders (spalla manica a camicia). Personally I really like, how the jacket shoulders can become smooth like a second skin with the shirt sleeve shoulder construction. However, I realize that they might not be the better solution on a formal navy blue suit or formal charcoal suit or a dinner jacket, which perhaps need more straight lines. Moreover men with sloping shoulders should be carefull with the construction.
