Material is unknown. This is a girl's ceremonial kimono for Hatsumiyamairi (a Shinto shrine visit celebrating a baby's birth). It has a very gorgeous and elegant, lovely design. It's a girl's celebratory kimono with gentle colors and very auspicious patterns and colors. A long undergarment (nagajuban) is not included, but I think there will be no problem if you use it for Hatsumiyamairi as a ceremonial kimono. Size: Length 97cm Sleeve length 47.5cm Sleeve length 56cm There is a small stain on the lining (Image 14). Otherwise, it is very clean. Therefore, I have set the price low. Please refrain from purchasing if you are concerned. Please note that the shipping method may be changed to Yu-Yu Mercari delivery. I have other items for sale as well.
