This is a silk (正絹) double-layered (袷) Nagajuban (long undergarment). It has a lovely pattern. The base color is a pale yellow with a pattern featuring blue, green, and red designs. The collar (半衿) is an embroidered one that I hand-sewed on using a piece I had at home. Measurements: Length 136cm, Sleeve Length 52cm, Front Width 25cm, Back Width 30.5cm. It has been aired out and treated with a deodorizing and antibacterial agent.
