As described, this hat is a petite sized hat. My head measures 21 inches and I have thin short hair. The hat just fits. Suggest sizing up if your head is larger or if you have a lot of hair. You may want to measure your head how you are going to wear the hat. If you plan to tilt it back then measure where the hats diameter will sit. Well made hat that truly pops back into shape after packing. I added a strap as I'll be wearing the hat when boating. Simply inserted a nail in the weave and twisted it until it stretched to be big enough to insert a 1/4 inch round, 54 inch shoe lace. Threaded the lace starting on the inside of one side, across the front of the crown and through second hole on the other side of hat. Added a push button clasp for security. The multi tan is a nice neutral. Love the depth of the brim as it protects my face and neck when worn upright and the edge can be flattened to extend coverage. Never liked hats as they always seemed to look, well goofy on me. However, a well fitted hat  makes a big difference. This hat is cute and flattering.
