Bucket hats probably started has practical fishemens hat in some oiled fabric, but were adopted has fashion hats in the 1960's.
Also known as session hat, fisherman's hat, or Irish country hat.
I've had this hat for a least 27 years as went with me to Thailand 1989 as can be seen in the photos below
My taste in clothing has got a little duller since this photo below with the very sun burnt legs to match the shorts.
