70’s/80’s Olive Green Cotton Bush HatWork your sexy inner Crocodile Dundeezy! This hat is so so so so so cute on! I'm not an expert but from research, it seems to be made of Cotton Oilskin. The inner circumference is 21" and I posted a picture of the width and length. NOTE: 21" is on the smaller size for hats. Wrap a string around your head for size comparison! Stop faffing about and buy this hat! (Had to throw some Aussie slang in. I couldn't resist)
