Let’s see how to draft the pattern of this 50s halter dress.
Start from the pattern of a basic dress.
On both bodices draw the necklines and prepare it for the dart manipulation as you see in the photo.
On the skirt erase the darts.
Cut the pieces separate and close the existing darts on the bodices – open the volume at the front shoulder dart and extend the skirt pieces towards the side for the gathering.
Attach the back neckline to the front one and mark it as a whole bigger piece with pleats at the back.
Add a rectangular piece for the pocket and you get the finished pattern.
