Nipples should be located at the center of each breast. The nipples are connected to the mammary glands, which produce milk in women. Interestingly, during one study 1,000 men and 1,000 women were interviewed to determine the preferred nipple-areola location. The study concluded that both men and women prefer nipples to be “in the middle of the breast gland vertically and slightly lateral to the midpoint horizontally.”
