When it comes to supporting the girls, we've got just about every kind of bra out there to keep our boobs looking lifted and supple -- strapless, sports bras, lifting, padded, lace, special occasion, you name it. It's one of the first things we put on in the morning and one of the last things we take off at night. But a new study claims we might be wasting our time wearing one. Instead, wearing a bra may actually be causing breasts to sag.

According to Mommylish, a new French study of over 300 women conducted by Jean-Denis Rouillon, a professor at the University of Franche-Comté in Besançon, bras may not be helping our breasts from sagging after all.

"Medically, physiologically, anatomically, the breast does not benefit from being deprived of gravity," he said. The study took 15 years to complete and found that for each year a woman didn't wear a bra, they developed lifted, firmer breasts.

He went on to report the findings that in the long run, it was women who did not wear bras that benefited the most because they developed more muscle tissue to provide natural support. When a woman wears a bra, the restrictive material of it can prevent muscle tissue from growing, which may then actually lead to accelerated sagging, sooner.

But do other doctors agree? "On the surface, this claim seems plausible," says Dr. Stafford Broumand, an NYC-based plastic surgeon, in regards to the theory that breasts can sag due to bra-wearing. "For younger women, not wearing a bra will lead to increased collagen production and elasticity, which improves life in a developing breast. Also, tension on the connective tissue and ligaments supporting the breast can be beneficial to help prevent sagging."
