The fabric is a 14 ounce Japanese selvedge over-dyed black over indigo blue over a slubby yarn. This is a great Japanese fabric made by Kurabo that has been over-dyed by them. Very unique and should have some great wear and fade characters. The denim jacket will be sewn with our vintage stitched rmc tsunami rainbow embroidery and have the original rivet construction. The out seam will be sewn with a clean flat felled seam so it will look special and great for style.
