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. The bow measures approximately 4" across. The exposed stitching detail and a raw edge is signature Baby Bling! A fun feature of the prints is our logo printed to complement each design. This style is sewn in two pieces and can be taken apart for hand washing or to mix-and-match.
