From Simplicity:
Sized for stretch knits only: Jumpsuit with pants stitched to bodice at elasticized waistline has twisted draped front with deep v-neckline and long dolman sleeves.
Recommended Fabrics: Cotton and wool jerseys. No provisions made for lengthening or shortening this pattern. Extra fabric needed to match one-way design fabric. For pile, shaded or one-way design fabrics, use with nap yardages/layouts. Not suitable for stripes, plaids or obvious diagonals.
Sizes: (6-8-10), (12-14-16)
