This product named COTTON, is inspired by willow catkins drifting in the wind under a winter's snow. The outer layer is made of 100% pure mulberry silk, using the traditional Xiangyunsha technique, while the inner layer is lined with high-elastic cotton. The edges are trimmed with mink fur for added warmth. It looks relaxed when layered under a sweatshirt, and adds a touch of luxury when worn under a coat. The garment requires minimal washing, making it a blessing for those who prefer low-maintenance clothing. If washing is necessary, please hand wash in cold water and avoid direct sunlight and ironing. Suitable for all body types. This is more than just Xiangyunsha; it represents a thousand-year-old plant dyeing technique, a fusion of Chinese history and culture with modern Chinese design.
