Slip into something more comfortable: The OnePiece is perfect for occasions like this.

Jumpsuits may have taken over the Fall 2011 runways from Chanel to Yves Saint Laurent, but if you're looking for an option that's a little more lounge friendly than that spike-sleeve 3.1 Phillip Lim number, allow us to introduce the OnePiece.

Snuggie, step aside: This fleecy zip-up isn't just for the sofa—at least, according to Thomas Adams, who co-founded the line (now a favorite among celebs like Sarah Jessica Parker, Kate Moss, and Jude Law) along with his fellow Norwegians Hernik Nøstrud and Knut Gresvig.

"Me and my two partners had the idea on a Sunday, hung over!" Adams tells FashionEtc of the initial flash of fashion genius.

The trio wanted something ultimately comfortable—like their favorite sweat suit, minus the constricting waistband. They initially experimented by sewing together a sweatshirt and sweatpants. A hood here, a zipper there, and voilà: In 2007, the OnePiece was born.

At first, they only made a few for their friends. "Then I wore it outside to a party once, a solid purple one, and no one had ever seen anything like it," says Adams. "I was out in Norway, and everyone was like, 'What the hell are you wearing? Where did you buy that?' That's when we realized we would have that support. It became a fashion statement!"

Adams insists, however, that OnePiece isn't trying to join the ranks of the aforementioned Chanel and YSL.

"We of course look at fashion, but mostly we just design stuff that we think is cool," he says. "It's much more fun making styles you'd wear yourself—and many things you see in the fashion world we wouldn't wear ourselves." (Adams didn't keep up with the Fall 2011 shows, though he does cite Acne as a favorite. "They make a lot of cool stuff," he says.)

Next up for the brand? A range of OnePieces that may include "shorts, hot pants, hoodies, different materials … We're not saying too much about what's coming, but we're working on more things," says Adams.

"People have so many opinions about it—they love it or they hate it," he says of the line, which is sold at Harrods, at two stores in Sweden, and at onepiece.com (an L.A. flagship is in the works). "That's why it's gotten so much attraction. People get so involved! It's fun to see."

Of course, inquiring minds needed to know: What do Adams and his cohorts wear when they're not in the OnePiece? The answer isn't surprising.

"I'm always wearing the OnePiece!"
