This is a two-piece Nagajuban (long undergarment) with a floral embroidered han-eri (detachable collar). The Nagajuban is a separate type, consisting of a semi-juban for the upper body and a susoyoke (petticoat) for the lower body. It's easy to put on and the length of the hem is also easy to adjust. It also comes with a stylish han-eri. - Size: L - Color: White and light blue - Design: Floral embroidered collar - Style: Two-piece Nagajuban - Material: Sleeves: 100% Polyester Body: 100% Cotton Susoyoke: 100% Polyester Waistband: 100% Cotton It can be washed at home. I used it when I was 160cm tall, but since it's a two-piece, I think it can be used by people who are about 10cm shorter or taller than me. Thank you for looking.
