 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.
