Ladies, listen up.

If you’re not wearing the right type of bra, you could be damaging your breasts without even realizing it.

Researchers from the University of Portsmouth in Hampshire, England found that wearing the wrong “support system” could lead to fragile ligaments in the breasts becoming irreparably stretched, the Daily Mail reported.

They found up to 95 percent of women are at risk — mostly because they are ignorant or embarrassed about their true bra size, according to the report.

Researched concluded this after they gave 100 women a treadmill test.

During the past three years, the team studied about 50 bra designs. What they found was that with most bras women’s breasts move up and down, in and out and from side to side, shifting an average of 8.26 inches, during exercise.

The problem is that most bras are designed to limit just vertical movement, the Mail reported.

"Many women have strong preferences for certain styles of bra and won't buy anything else,” Wendy Hedger, a researcher told the Mail. "In sports bras, for example, many women won't buy a bra that resembles their everyday bra — they think if it can't be pulled over their heads like a crop top, then it's not a real sports bra.”

This is not true, Hedger said.

“Many sports bras do up at the back in the same way as a traditional bra and do a very good job of supporting women.”

The bottom-line, choose a bra that is going to support your breasts whether you’re walking down the street or running on a treadmill, researchers said.
