A NagaJuban is worn as an undergarment beneath a Kimono or Yukata, similar to an undershirt in western clothing . A NagaJuban is two pieces consisting of top (Han Juban) and a bottom (Susoyoke). The undergarment keeps the kimono or Yukata from being soiled. This NagaJuban has a narrow collar, polyester top and bottom, and cotton lace. Perfect for under a formal NagaJuban or a Kimono or Yukata without the white collar showing. This is very light, silky soft and comfortable.
