This is a baby's ceremony wear. I dressed my baby in this when we left the hospital after birth. The size is for babies 50-70 cm tall and weighing 3-9 kg. It's made by Alps Kawamura, made in Japan, and is 100% cotton. It's thin and breathable, and when wrapped in a white swaddle, it creates a pure white of happiness. Please use it with the matching baby ceremony hat. The hat is CELEC brand. There is a very faint stain on the collar. It may be difficult to see in the photos, so please refrain from purchasing if you are concerned about it.
