A Brooklyn college student who was among 12 people struck in a wild shoot-out at a packed Brownsville block party escaped with little more than a scratch — because her bra stopped a bullet.

“When the EMS unhooked her bra, the bullet was just sitting in the bra strap and it just fell out,” said Odessa Watson of her 21-year-old daughter, Daniesa Murdaugh. “It got caught in there.”

“There were fragments still in the skin, but it was a graze,” Watson continued. “It was a regular bra. The threading of it, because we’re thick girls, is thicker. And it got caught in the back part of the bra.

Murdaugh, a Queensboro College Student, escaped what could have been a life-changing — or life-ending — injury when at least two gunmen opened fire at the annual Old Timers Day event Saturday night.

“We were told to run and when I turned around to see, I was hit in the back,” recalled Murdaugh. “I was so scared.”

Murdaugh was one of a dozen people struck, including one fatally — reputed Bloods gangbanger Jason Pagan.

“I know someone was looking out for me,” added Watson. “I pray for my children every single day.”
