This super wide-brimmed hat will glamorously shield you from the sun! Crown Circumference: 23.5 inches (when measured on the outside of the hat). There is an interior elastic band with a circumference that is about 22 inches, with slight variability due to the fact that these are handmade. Brim Length: 7 inches (18 cm) Crown Height: 4 3/4 inches (11.5 cm) This hat ships with a long ivory grosgrain ribbon. NATURAL MATERIAL: This hat is woven with real palm tree leaves, so there is natural color differentiation within the weave. CARE INSTRUCTIONS: If your hat is in need of reshaping, use a household steamer to mold the brim and crown into your desired shape. Store your hat in its original packaging or gently stuff its interior with colorless tissue paper.
