Garment Measurements | Virtual Size Chart


The Studio D’Artisan SP-093 Ishikawadai Denim Workshirt is a limited 45th Anniversary piece produced in an exclusive 12.5 oz. Japanese Selvedge Denim using a vintage spinning machine to be a vintage-inspired, soft, and hearty style-forward heritage collector’s item. This denim is loomed from ring-spun cotton produced by the oldest operational spinning machine in Japan from Ishikawa Seisakusho Co., manufactured in 1953. It operates at exceptionally slow speeds with less tension on the cotton fibers. This yields an all-season, heavyweight Japanese selvedge denim with intense character and a flexible hand that has been washed and moderately rope dyed on the warp for a medium blue that will fade and contrast to a grey weft with a personalized patina. The Studio D’Artisan Workshirt has a classic slim fit that works for various body types, and signature details are elevated from vintage originals like buttoned chest pockets and barrel cuffs, finished with custom urea buttons, and accompanied by a 45th Anniversary Ishikawa commemorative tote. The SDA Ishikawadai Denim Workshirt is completely chainstitched throughout with inseam run-off, a selvedge gusset, and felled seams, providing durable, old-world provenance that allows a journey into the ancient past by way of present styles, transported to you by a standout 40-year-old producer of heritage denim.
