This is a black faux leather bucket hat from BEAMS. It's a good condition item, kept in a dark place with the tag attached. The size is indicated as 57 to 59cm, and there's a Velcro size adjuster on the inner circumference of the hat. Please refer to photo 8. Even with my large head size of 61cm, I can wear it normally at the maximum adjustment. The diameter of the hat at its maximum size is approximately 20cm, measured by a layman. Please check the condition of the item in the photos. Please refrain from price negotiations. It will be carefully folded, wrapped in a plastic bag, and made compact for delivery. Please refrain from purchasing if you are sensitive to items that have been stored by an individual.
