Purchased from Bobo Choses Japan online. The collar around the neck is very cute. You can wear it stylishly even with just one piece in the summer! 95% organic cotton, 5% elastane. The material is soft and feels good on a baby's skin. The original price was about 7500 yen. Length about 40cm, width about 22cm. My child wore it until they were about 1 year old! Worn about 5 times. There are no noticeable stains, but please refrain from purchasing if you are sensitive to used items.
