This is such a beautiful orange fascinator or hatinator. It has a round pill box style base with a stunning layered flower and delicate feathers. The hat base measures 14.5cm(5.75") in diameter and the height is approximately 10cm. It has a narrow satin covered hairband that is so comfortable to wear. A lovely fashion accessory for a wedding, Ascot, garden parties and many other occasions. This hat is suitable for the Royal Enclosure as it meets the 4" diameter base that they ask for.
