From Seamwork:
If you sew the Campbell jumpsuit, all you need is a pair of shoes, and you’ll have a really stylish outfit. This jumpsuit has a relaxed fit with tapered legs and a waist-cinching belt. A notch collar and center front button closure will help you perfect your sewing skills, and there are pockets at the breast, back, and side seam.
Sew Campbell in medium-weight wovens like cotton twill, linen, denim, canvas, and rayon twill.
