Donna Karan vintage men’s double breasted jacket

Excellent preowned condition no signs of wear at all no issues at all the material feels like cashmere totally lined. As per the above chart I’m thinking this is a size 40 it seems to have been custom-made but the measurements are with the garment laid flat shoulder shoulder 19 1/2 inches chest 22 1/2 inches waist 20 inches outer sleeve 24 inches inch inner sleeve 16 inches back length from the nape of the neck to the end of the garment 30 1/2 inches front length from the shoulder to the end of the garment 31 inches.
