These simple and sweet cotton bows measure 2.75" x 2" and come attached to your pick of a "one size fits most" nylon headband or a "sized to fit" headband. Both styles of elastic measure approximately 1/4" wide.
NOTE... nylon bands (ONE SIZE FITS MOST) only come in white, ivory, nude, and black
*For the best fit I recommend sizing down around 1/2" smaller than what the head measures.*
