Headwrap Sizing Options: Newborn / Preemie: (11-13' head circumference) Baby 0-6 Months: (13-15' head circumference) Baby 6-12 Months: (16-19' head circumference) Youth 1-5 Years: (19-21' head circumference) Preteen To Adult 6 and older): (21'+ head circumference) (Please let me know in the notes section if you need a specific size or larger size. I CAN and WILL accommodate you) * It is recommended that you order 1 inch down from your head circumference especially when a large bow is involved because the materials used have good stretch capability and the bigger bows can weigh the wrap down.  PLEASE NOTE: NYLONS & HEADBANDS are all ONE SIZE
