It is 100% cotton. I used it once for a baby's first shrine visit and have kept it at home since. The size is free size, but since it's for ceremonies, I think it's around ~70cm. I only selected a size because it was required, so please understand that. It's an A-line dress. The fabric is slightly thin. Since it's a personal inspection, there may be oversight of scratches or stains. It has been folded and stored, so there are wrinkles overall. Please understand that it is a used item and has been stored at home for a long time. It will be simply packaged. Returns are not accepted. Type: Seasonal/Event
