What。Designer women\'s special Great Gatsby party event or out on the town. The hat is made from all-natural material fibers in a smokey grey color. I have embellished this hat by covering it with a sequined fabric in a floral motif. For a Art deco look I have used a complementary gray velvet for the band accented with a beaded and silver thread applique. Perfect for a comfortable and elegant wear. Medium (22 to 22 1/2\") This hat is made to fit a medium size. There is NO adjustment which means this is a perfect fit and will not have that crumpled back which is what you get with those cheaper adjustable type hats. How to measure your head.... Take a cloth measuring tape around the back of your head and over your ears. Have the tape meet on your forehead where you want the hat to sit. Do this several times as an accurate measurement is important.
