KNOW YOUR BREASTS
A guide to classifying your breast separation
Breast separation between women’s breasts really does vary widely. This is the horizontal distance between your two breasts at the center of your chest.
How much or how little distance you have between your two breasts can determine if you will be able to achieve touching cleavage (that vertical fold line created when breasts touch), how a bra will fit you, and if an underwire bra will be comfortable.
