Let’s see how to draft the pattern of this bodice.
It’s an advanced dart manipulation with the addition of some volume at the neckline.
Here you see the front only, as it matches a basic back with darts. It can be used for dresses, blouses, tops…
The one you see in the photo was realized with a satin but any fabric can be used. Mind that the more drapey the fabric, the softer you will see the weaves; the stiffer the fabric, the more ‘standing’ the weaves will be.
