So this Is how I am thinking of doing my hair for sweethearts dance. I am for sure going to my hair dresser to do my hair. If I wanted my hair like this what would I tell my hair
Dresser? What is the name of this hair style? If there is no name how would I describe it to her to make my hair look as close to this as possible?
