This product, named INKSTONE, draws inspiration from the inkstone used in Chinese calligraphy. The garment is made of 100% mulberry silk, a pure natural black gauze, resembling ink spread across Xuan paper. The traditional three-wash, nine-boil, and eighteen-day drying process of yam dyeing imbues the fabric with the sound of grinding ink. This garment eliminates the hassle of washing, making it a boon for lazy people. If washing is necessary, please hand wash in cold water and avoid direct sunlight and ironing. Suitable for all body types. This is not merely yam yarn; it represents a thousand-year-old plant dyeing technique, a fusion of Chinese history and culture with modern Chinese design.
