This is a used nagajuban (long undergarment for kimono). I was told the material is silk, but I'm not certain, so I'll list it as unknown. A purple cotton han-eri (collar) is sewn on. Measurements are approximate, as they were taken by a novice. Please use them as a reference. Length (from shoulder): Approximately 120cm Sleeve span: Approximately 62cm Sleeve length: Approximately 46cm The base color is off-white with a pinkish-red pattern. It is a single-layered type. It will be folded compactly for shipping. Instant purchase is welcome.
