Bra Fence, Idea By John Lee, 66-year-old Farmer, New Zealand

In a study conducted in the United Kingdom of 103 women seeking mammoplasty, researchers found a strong link between obesity and inaccurate back measurement. They concluded that "obesity, breast hypertrophy, fashion and bra-fitting practices combine to make those women who most need supportive bras the least likely to get accurately fitted bras." This led women in the study to choose too large a cup size (by a mean of three sizes) and too small a band size (by a mean of four inches). Other studies found that the most common mistake made by women when selecting a bra was to choose too large a back band and too small a cup, for example, 38C instead of 34E, or 34B instead of 30D.
• Ptosis (sagging)
Anatomically, the breasts are composed of soft, glandular tissue, with few support structures, such as connective tissue. Breasts are composed of the mammary glands, which remain relatively constant throughout life, as well as the adipose tissue or fat tissue that surrounds the mammary glands. It is the amount and distribution of adipose tissue and, to a lesser extent, glandular tissue that leads to variations in breast size. In addition, the breasts contain ligaments, although their exact function as related to breast support has not been agreed upon by experts. These ligaments, and the overlying skin (referred to as the dermal brassiere) help determine the resulting breast shape.
As the breasts mature, they fold over the lower attachment to the chest wall (infra-mammary fold), and their lower (inferior) surface lies against the chest wall when vertical. In popular culture, this maturation is referred to as "sagging" or "drooping", although plastic surgeons refer to it as ptosis. The surgical procedure to lift the breast is called mastopexy.
