New York- No jacket required for this members-only dining club – and no shirts, skirts or underwear, either.New York nudie foodies have turned their “clothing-optional dinners” into the city’s latest dining trend. There is but one rule for the au naturel gatherings: no hot soup.

Created a year ago by nudist John Ordover, the club gathers once a month at a swanky city restaurant for private meals in the buff. They check everything at the door – especially their inhibitions.

On Thursday, the club gathered for a stripped-down feast at John Barry’s restaurant on W. 38th St., even as temperatures outside fell below 20 degrees.

“Just turn the temperature up a little bit and you’re totally comfortable,” said Ordover, 42. “It’s nice to have something to do when it’s winter, when all the beaches are cold.”

Clothing-optional dinners have become so popular that organizers now get approached by restaurants that want to host their private parties, which require advance registration and covered windows.

“If you actually go to a nudist environment, it is the least sexual environment you can possibly imagine,” Ordover said. “Sexiness is inappropriate nudity, but if everyone’s supposed to be naked, it’s okay.”

The group’s next event will be an “Easter bonnet” on March 26, which will be held at a restaurant on the upper West Side.
