It doesn't matter if you're Irish or not, because you'll look the part in this velvet leprechaun top hat! This soft green hat is 100% polyester and has a circumference of approximately 24" on the inside. It also has black mesh on the inside to keep it in place. The brim has a wire frame to keep its shape. The gold foam buckle is attached to the hat. A great St. Patrick's Day hat at an even greater price!
