Most of the acorn hats I found were for children and infants, but I was fortunate enough to find this adult acorn hat from etsy seller talk2thetrees. It's a perfect fall hat for the quirky accessory lover. I like how, while it does look like an acorn, it doesn't look costumey, and still plays off well as a fashion accessory.
I adore the colors of these earrings from forthecrossjewlery. I feel it's truly been infused with autumn. The added acorn gives it that extra seasonal touch. It's are the type of accessory that would be bound to get compliments.
