I really like this hat, and found the fit to be just right. You do need to be very careful with your cutting and sewing of this though. Since the crown is made up of 6 seams, if you are off by only 1/8" you will get a hat that is 1 1/2" too big which is a lot bigger for a hat since an adult head is not much bigger than a toddler's head (my big head is only 2 inches bigger than my 2 year old son's).

I only interfaced the brim of the hat becasue I don't like the way the crown feels when it has interfacing in it. The wide brim on this hat makes it a great sun hat IMO.
