Child's cap, 54cm. Purchased at a hat shop in the Aeon specialty store area. The color in the second photo is the closest match! There's a soft wire in the brim, so you can change the shape. Size is adjustable. It's very cute, and my daughter loved wearing it. There's some fading, but it's still in good condition. Washed. Please understand that this is used children's clothing. Thank you.
