Please note: the size of this hat is not marked. It is too small for my head (adult woman) and is a tight squeeze on the mannequin head. So I am assuming it is a childs hat. This stylish girls' sun hat by Sun Shade is the perfect accessory for any active or casual occasion. The adjustable size and vented design ensure comfort and breathability, while the pony tail opening and chin strap provide a secure fit. The pink color and mesh fabric type make it a fashionable addition to any outfit, and the mixed material adds a touch of durability. This sun hat is a must-have for any young girl's summer wardrobe.
