Thank you for viewing. This is a two-way dress-all with an embroidered round collar design, made of sturdy yet soft 100% cotton material, gentle on babies. The size is 50-70cm, so it can be worn for a long time. I wore it when I was discharged from the hospital and for the Hatsumiyamairi (Shinto shrine visit for newborns). It has been soaked and washed, but there may be some slight yellowing on the collar. Please understand this.
