This item is from about 35 years ago. I'm not sure of the material. I wore it once, had it dry-cleaned, and stored it in a paulownia chest. The long undergarment (nagajuban) has many visible stains, especially on the ties and shoulders. Length (back): 136cm Shoulder width: 24cm Sleeve width: 32cm 裄丈 (Yuki length): 64cm Back width: 30cm Measurements are approximate! There are stains, but there is also an obi (sash). (See photos)
