I only wore it once for the Hatsumiyamairi (a traditional Shinto ceremony for newborns). It's a white romper with a frilly collar. The cute design makes it perfect for when you leave the hospital or for special occasions. The size is 50-70cm, and the weight is 3-9kg. It's made of soft cotton, so it feels very nice to the touch, and I think it's comfortable for the baby to wear. Because of its simple design, you can wear it not only for events but also as everyday wear in the coming chilly days.
