I have a few pairs of Pajama Jeans and the ones I bought off of Amazon fit a little different than the ones I bought straight from the Pajama Jean website....a little snug in the hips and waist but not enough to send back or worry that I somehow put on some pounds.  They also smelled AWFUL!!  I don't know if it's the dye or what but I had to wash these a couple of times and the smell is still there but not as much -- kind of smells like moth balls.
