A nightcap that can be worn during a good night's sleep to prevent friction, static electricity, and sleeping habits and reduce hair damage. Sister is a new design born from the voices of hair creperie users. The design is designed for those with short to shoulder-length hair. The point is that you can easily cover it by tying a ribbon under your chin and adjust the size, making it difficult to take off. Plain color scheme that is easy to match with pajamas. The piping and ribbon colors accentuate it. The side that touches the hair is 50% silk and 50% cotton. The outer material is 100% cotton. Since it is a natural material, it can be worn comfortably all year round. <MATERIAL>COTTON, SILKmade in china photos taken at the "Hotel Noum OSAKA". photos taken at the " L Y U R O Tokyo Kiyosumi".
