Kardashian Family -- We Sold Our Bras To Raise $$$ For Vets

Kim Kardashian's bra is capable of supporting a whole lot more than her boobs ... it's also helping support U.S. military families.

The Kardashians organized the charity yard sale yesterday -- for their reality show, natch -- to raise money for two charities -- the No Kid Hungry Foundation and the Greater L.A. Fisher house -- which provides housing for families of wounded warriors.

Our Kardashian peeps tell us ... the family raised about $6K by selling their old lingerie, clothing, artwork and household goods ... and the family will match the loot so the total take is $12K.

Tim Byk, founder and exec. director of Fisher House, tells us, "They reached out to us, they found us. Maybe they will make it over to the house for a pizza party."

Cash aside ... we're told the Kardashians are also donating all the items that didn't sell yesterday ... to the Fisher House families.
