It is a very professional technology that ordinary tailors can't afford, because leather can only be sewn after cutting. Unlike cloth, leather can't be folded directly because it will bulge. When the leather coat becomes smaller, the trim leather needs to be polished so that it won't bulge when sewing. In addition, leather clothes need to be re-cared after being re-cut and stitched, which is also the difference between cloth and clothes. Of course, the method of cutting is also different from cloth. So if you really want to cut it, you must find a leather care shop like a small shoemaker in Nanjing.
