This is a wide-brimmed fedora hat. It's a very beautiful item with no signs of use. Inner diameter: Approximately 59cm Material: Although there is no label, I believe it is wool. The inner circumference size is measured with a measuring tape along the edge of the sweatband on the back, so please allow for some margin of error. This item is also listed on other auction and flea market sites. Please note that the item may not be available. 26/2
