If you ever thought you didn't have the swagger to pull off a jumpsuit, fear not: One Direction are here to help. The boys have lent their faces and name to OnePiece, and there's video of the boys in the onesie pajamas -- and it's kind of amazing.

In a behind-the-scenes look at the boys' commercial, we see them putting handprints all over one another. They're smacking one another's butts (or "bums," as the Brits would say), chasing each other around and generally making wearing a onesie look a lot cooler than we'd originally thought. Our favorite parts? Anything that involves Harry Styles screaming -- and be sure to watch the clip until the very end!
