Bonnet Size: 90 The image of a bonnet is strong for babies who still have thin hair, but personally, I want to put it on even after they start walking steadily. I absolutely love my child's face peeking out from the center wrapped in cloth. Pulling the string tightens the neck, so it fits without the back of the neck lifting. The tag's position is an adorable bonnet that reminds me of a school swimming cap. [Material] 100% Cotton Thank you.
