Baby Bling Bows Printed Fab Bow Headband in Autumn Layers. This headband is one size fits most and the size cannot be adjusted. The headband is sewn at a 6.5" diameter (13" circumference), keep in mind that measurement is before it stretches. We feel this is the perfect size for our soft material to fit a newborn and stretch comfortably as she grows into childhood. The bow measures approximately 4.5" across. All edges of this style are raw and are intended to roll. This style is secured with adhesive once tied and is not meant to be untied.
