Hat Sizes in inches: You can use a tape measure (or a length of string that you will have to hold up to a tape measure) to determine the length. Place the string or tape around your head about 1/8 above your ear, across the mid-forehead, completely circling your head. Hold the tape firmly, but not too tightly.
Character hats are $15, but more intensive ones can be priced higher.
Also washer dryer safe unless otherwise noted
