Available sizes: preemie, newborn, 3 to 6 month, 6 to 12 month, 12 to 18 month, age 2 to 4, age 5 to 8, age 9 to 12, and adult. In your message to the seller, please specify the SIZE and INITIALSin the order that you want them for this personalized item. Available colors are viewable at the right. Example: 12 to 18 month, hunter hat with navy design for the initials HRH. Please note that the monogram reads first name initial – last name initial – middle name initial with the last name initial in larger font in the center. Example: Cody Lee Hart’s monogram would appear as CHL with H in a larger font than C & L. If it makes you more comfortable, you may include the first, middle, and last names in order to ensure an accurate monogram, for example: C first name, H last name, L middle name.
