Yes: 15 year study suggest going Braless is better :)

According to a 15-year study conducted by French professor Jean-Denis Rouillon (MUST HAVE BEEN A FUN 15 YEARS, lol! :P), wearing a bra doesn't prevent sagging breasts and may actually increase boob drop.

Our first results confirm the hypothesis that the bra is a false need," Rouillon told France Info. "Medically, physiologically, anatomically, the breast does not benefit from being deprived of gravity. Instead, it languishes with a bra."

The 15-year study involved 330 volunteers between the ages 18 and 35. Researchers measured their breasts using a slide ruler and a caliper and recorded any changes throughout the study period.

Women who did not wear bras had a 7 millimeter lift as measured from their nipples each year. Their breasts were also firmer, and their stretch marks faded. There was also no evidence that the bras helped get rid of back pain.

The researchers believed that wearing bras prevented the growth of breast tissue, which lead to deterioration of the muscles that support the breasts. If you don't wear a bra, the muscles are worked-out more, the findings suggest.

I mean, I agree about sometimes is a good idea to wear a bra, but Thinking about the logic of bra wearing is a bit depressing. It's more socially inculcated hatred of our bodies really, isn't it?
