Purchased in the winter of 2023. Worn by a child born in March for their discharge from the hospital and first birthday. Fit just barely at one year old, weighing just under 9 kg. Think of it as a thick T-shirt material. How about it for those expecting a baby in early spring, or those who want to use it right away? It might also be usable for older siblings' Shichi-Go-San (ceremony for children aged three, five, and seven). It will be cold outdoors in mid-winter, so please adjust with innerwear, swaddling blankets, etc. This is a used item that a child has worn, so please understand. #newborn #1stbirthday #ShichiGoSan #formalwear #celebration (Quoted from the official website) This is a 2-way all-in-one with a knit vest, perfect for special occasions and celebrations. You can enjoy a special look with a neat atmosphere. The ribbon tie can be attached or removed as desired. The knit vest and 2-way all-in-one can be separated, so it is also recommended to coordinate them separately with other items.
