New York- Not even a beautiful woman dancing topless can stop traffic in Times Square.

Julia Wiedeman, 24, of Brooklyn, found that out yesterday when she stripped off her sweatshirt at the crossroads of the world for an “art project.”

“People don’t even look,” marveled photographer Jordan Matter, 38, of Washington Heights, who has shot 40 women topless around New York for his “Uncovered” project – online at www.jordanmatter.com.

In over 2-1/2 hours in various spots in Times Square, the red-haired beauty endured a few vulgarities and ended up in a few tourists’ snapshots. But most people walked right past.

“It’s just boobs,” shrugged Wiedeman, a comedian and theater director. “So what’s the big deal?”

When Matter started his project he expected to document the disruption caused by topless women in everyday places – but found just the opposite.

“I tried to photograph mayhem, and there wasn’t any,” he said. In former porn capital Times Square, almost everyone took the free show in stride.

“Whatever,” shrugged Brenna Tooley, 20, of Sherman, Tex.

“Nobody really cares,” said Joe Davis, 41, of St. Louis.

“I’m not surprised,” said Rick Gillis, 57, of Kansas City, Kan. “Only in New York.”

The only disapproval came from a group of tourists from Toronto.

“That’s supposed to be for marriage, for a man and a wife,” said Joey Montague. “That’s something intimate, not for everybody to see.”
