PRESIDENT KENNEDY'S GRANDDAUGHTER ACCIDENTALLY WEARS JACKIE'S BLOODSTAINED PINK DRESS TO HALLOWEEN PARTY

"Everybody had a real good horse laugh over it; it was just one of those magic moments, and a good time was had by all!"

NEW YORK - It was the mix-up of all fashion mix-ups when seventeen-year-old Tatiana Celia Kennedy Schlossberg, granddaughter of the late Jackie Kennedy Onassis, accidentally wore to a Halloween party the bloodstained pink outfit Jackie adorned the day President Kennedy was shot in Dallas in 1963.

"It was the damnedest thing," laughed family friend Mike Giunta. "Tatiana was looking for a scary outfit to wear to the party, and she came across the pink outfit in the attic, you know, stained with the blood and all that, so she thought it would be just perfect. I can't help but chuckle just thinking about it."

Giunta explained that when Tatiana walked into the party, one of the the kids told her what she'd done and "everybody had a real good horse laugh over it, especially Tatiana. A good time was had by all."

But the real hi jinx didn't start until a young woman showed up dressed like Marilyn Monroe. "It was a riot," explained Giunta. "Tatiana, wearing that dress, was drawn right over to her. She got up in Marilyn Monroe's face and slapped her. It was a real cat fight, brother, I'm telling you!"
