Young Teen College Girl Without Brassiere

Pare away the fiction and fears, and the pros and cons of the bra come down to this: If a woman chooses to wear one because it makes her feel good-more supported, more under control or just prettier-more power to her... Haycock suggests that women let pain be their guide when deciding whether to wear a bra during exercise, and when choosing a particular style.
While large-breasted women may be uncomfortable exercising without a bra, Dr. Haycock said that “It’s not doing any lasting damage to chest muscles or breast tissue.” Her research found that “those who wore an A cup were frequently most comfortable with no bra at all."
There are some indications that wearing a bra may have an effect opposite to that which was intended. In a Japanese study, 11 women were measured wearing a standardised fitted bra for three months. They found that breasts became larger and lower, with the underbust measurement decreasing and the overbust increasing, while the lowest point of the breast moved downwards and outwards. The effect was more emphasized in larger-breasted women. This may be related to the particular bra chosen for the experiment, as there was some improvement after changing to a different model. These findings were confirmed in a much larger French study of 250 women who exercised regularly and were followed by questionnaires and biometric measurements for a year after agreeing not to wear a bra. While there was some initial discomfort at the first evaluation, this gradually disappeared and by the end of the year nearly all the women had improved comfort compared to before the study. The measurements showed firmer, and more elevated and youthful breasts. One example is given of a woman who had breasts that were uncomfortably large, and who had improvement after two years of being without a bra.
Breasts naturally change in shape and size as women age. There are conflicting opinions but no known studies to show whether bras actually delay or reverse the natural process. Health ethicists are concerned that plastic surgery and implants have altered our concept of what is "normal" and medicalised women's bodies by making the normal aging process a "disease."
