Approximately two seconds into my conversation with style icon Sarah Jessica Parker, she exclaimed, "Are you serious?"

It's not what you think. I'm not a crazed fan asking her to reveal the plot of the next "Sex and the City" movie. I am, however, shocking her.

With my pants.

At this point, it's noon on Friday, February 19, and we are at her fragrance launch at an incredibly cute dessert bar in New York City. I'm 60 hours into my experiment of wearing PajamaJeans -- 24 hours a day, 3 days straight -- during New York Fashion Week.

If you haven't heard, PajamaJeans are the newest addition to the "I didn't feel like getting dressed" family of -- insert air quotes here -- fashion. They caused a media stir earlier this month, and join Snuggies, Snuggle Suits, and, to a slightly lesser extent, jeggings, in the peculiar trend of clothing that caters to Americans who can no longer muster up the energy to get out of bed.

"We were noticing that people were wearing their pajamas on airplanes and in grocery stores. But a lot of people have mixed feelings about it because they think it's inappropriate and sloppy," The PajamaGram Company merchandising manager Stacey Buonanno told StyleList. "We thought, why don't we develop something you're comfortable hanging around the house in or sleeping in, but it looks acceptable when you go out?"

Thus, PajamaJeans were born -- and equipped with the catchy slogan, "The pajamas to live in, and the jeans to sleep in."

So I did just that.

The double-duty denim arrived -- fashionably late -- on the third-to-last day of Fashion Week. Their wash was darker than I expected, a deep indigo hue, and the exact color I prefer for my "real" jeans, since it has a slimming effect.
After parading the pants around the office with both pumps and boots, we decided the PajamaJeans look best tucked into boots. They have a slight boot cut and are a little short -- I'm 5' 7" and they hit just below my ankles.

The length is perfect for lounging around the house and pairing with sneakers. But at the judgmental tents, where New York Fashion Week is held, a boot-cut hem is the fashion equivalent of an open wound in shark-infested waters. So I baited them in over-the-knee boots.

And the style sharks bit.

I glided past one potentially vicious, clipboard-wielding PR girl after another, and not one batted an eyelash. Every editor, photographer, and makeup artist I shared my secret with was shocked to find out I was wearing pj's -- and dirty ones at that! Each agreed that they looked flattering and not at all like sweatpants or Snuggies. A top hairstylist even asked for my room number (ew!).

"They look so chic on you -- I love it," exclaimed Elle creative director Joe Zee, who has outfitted many celebrities. "They look like a sharp, clean, polished denim."

Designer Isaac Mizrahi even related to my pants -- err, pajamas. "It isn't easy to get out of bed, I have to tell you," he confided. "I'm an insomniac, and it's even hard for me to get out of bed."

The consensus? In the world of fashion, "Either you're in," as Heidi Klum would say, "Or you're out." And my pants were "In," for now. "I wouldn't call them the new black," said one editor who asked to remain nameless. "But they're not immediately offensive."

While the PajamaJeans' debatably stylish facade passed the test, their concept flies in fashion's face. Standard blue jeans were once the hallmark of comfort, but suddenly, in the sweatpants-clad US of A, that's not enough. Do PajamaJeans threaten to make every day casual Friday?
I posed this question to Mizrahi, who remained optimistic, comparing fashion to dinner. "If you have macaroni and cheese every night of your life, you want foie gras, eventually," he said. "Maybe it's human nature that we're afraid of everything, but eventually -- hopefully -- courage gets the upper hand, so you get out of bed, you get out of the Snuggies, you get into your pencil skirt and high heels."

"I'm always a big fan of something that can look slick and be comfortable," added Zee. "I don't think we always need to suffer for style every single moment of our lives."

Which brings me back to my discussion with SJP, who single-handedly launched some of the biggest fashion trends of the early aughts as Carrie Bradshaw.

After confessing that I was wearing pajamas in her presence, she incredulously exclaimed, "They look like jeans!"

Slightly perplexed, SJP took a long look at my PajamaJeans, then slipped into a Carrie-eque diatribe as she tried to grasp their meaning. "Are they for when you're feeling lazy at the end of a long day, or in the morning? I've never heard of that. It's really innovative."

She then summed up the thesis of my 72 hours of public pajama wearing in one neat sentence: "They look good on you, and that's really all that matters."

She's right. Whether we pull on $250 Ernest Sewns, $60 Gap 1969s, or $40 jeans that double as pajamas, the important thing is that they flatter our bodies, and make us feel sexy and confident.

Nobody but you has to know if you sleep in them.
