A new French study claims bras don't work and may be doing breasts more harm than good.
The 15-year study published this week found wearing a bra does little to ease back pain and could actually cause increased sagging.
"Medically, physiologically, anatomically, breasts gain no benefit from being denied gravity," the study’s author, University of Besançon Prof. Jean-Denis Rouillon, told The Local. "On the contrary, they get saggier with a bra."
Rouillon, a sports science expert, spent years measuring changes in the orientation of breasts in 130 women ages 18 to 35 for the study.
One woman who participated told France Info she hasn't worn a bra in two years and can "breathe more easily. I carry myself better and I have less back pain."
