Breasts Cleavage Girl

The International Federation of Associations of Anatomists (IFAA) has adopted the terms intermammary sulcus or intermammary cleft when referring to the area of cleavage between the breasts not including the breasts. For legal purpose it was noted by the United States federal courts that "anal cleft or cleavage" and "cleavage of the female breast" are so imprecise as to provide no guidance in defining them.
Lateral
When the lateral aspects of the breasts are uncovered, it is known as side cleavage, sidewinders or sideboob.
