Pajamas that Touch the Floor

Disclaimer:
I measured the Dude the other night for these, and discovered that he has the same waist and chest dimensions as his four-year-old cousin - but he has 6" longer legs and is 9" taller overall. No wonder his pants never touch the ground.
Not any more, kiddo!
 Based on the Simplicity 8493 pattern. By based on, I mean, I still hate the neckline. I've tried it as a V, now as an oval... Maybe I should try it with the buttons originally intended in the pattern.
Want to be really scared? I use the pattern for size 2...and just made the sleeves and legs (a lot) longer.
