These are one size fits all. they are really soft and stretchy , perfect for a baby head. I have 17 different colors. Our color chart is on the 1st picture in the listing. Features: * The bow size is 5 inches. * the width of the headband is about 3 and half inches. Wash Instructions: I do not recommend to use a laundry or drier machine on them. Preferably Hand wash and let them dry by themselves.
