The findings from a 15-year, longitudinal study of more than 300 women in France, suggest that breasts would gain more tone, and would support themselves, if no bra was used. Why? Bras appear to limit the growth of supporting breast tissues, leaving the breast to wither and degrade more quickly. In fact, women who stopped wearing bras experienced a 7mm lift in their nippleseach year that they did not wear a bra, and bra-less women developed firmer breasts, and stretch marks faded. And, in direct opposition to the myth that the bra eases back pain for women with larger breasts, not wearing a bra actually eased the pain, while wearing a bra did not.
