This headband is one size fits most and the size cannot be adjusted. We feel this is the perfect size for our soft nylon to fit a newborn and stretch comfortably as she grows into childhood. The exposed stitching detail and a raw edge is signature Baby Bling! This style is sewn in two pieces and can be taken apart for hand washing or to mix-and-match. Each headband is hand made in the USA, sewn and tied by women in our local community.
