Pajama Jeans: Because Spandex Cameltoe Never Looked Better
But in case you really need an explanation, Pajama Jeans are described by their manufacturer as "The style of your favorite jeans, together with the comfort of pajamas!" with the tag line: "Just because you're busy doesn't mean you can't look sharp!"
Hopes were that the trend would die (as most things do) after being featured on the View, but looks as though the $39.95 fugly cotton/spandex flares with puff paint and studs are making a return.
Fair enough, you're busy. Or maybe you really do like sweatpants as much as you hate getting laid.
