Reference garment: None. Design is entirely from the Armstrong book "Slip Dress with Slinky Skirt" (p500).
All steps recorded. You just need to choose your fabric.
Basic bodice block: Armstrong basic dress foundation (p44), and basic torso foundation (p449). You also need to refer contour guideline (p189)

Note:
- The skirt is not as slinky that I hope for. The book instructs to let the dress stretch overnight, but no way I will simulate that long. Perhaps I need to use different fabric.
