Thank you for viewing! ☺︎ This is a bonnet for kids. The photo shows it worn by a 3-year-old child. I hope this helps you with the sizing. As this is handmade, there may be slight variations in the pattern balance, and it may not be as perfect as a manufactured product, but I make each one with care. I also sell other handmade items, so I would be happy if you would take a look. ☺︎
