This product is called SECLUSION. This vest is made of 100% pure mulberry silk, specifically Xiangyunsha, and features delicate floral embroidery. It requires no washing; simply hand wash in cold water and air dry in the shade. Avoid direct sunlight and ironing. Suitable for all body types. This is not just Xiangyunsha; it represents a thousand-year-old plant-dyeing technique, a fusion of Chinese history and culture with modern Chinese design.
