The chiffon base has shoulder pads and the is neck trimmed with narrow double-fold bias tape. The back opening has a tulle overlay before adding the buttons and corresponding elastic loops. The armpits and left elbow are "torn" (okay, I used scissors).
The embroidered overlay is metallic silver thread on black tulle, which was then applied to the bodice with spray adhesive and then tacked down by hand.
The corset was custom-drafted. It laces up the back but also features a side zipper. I cannibalized a velvet skirt for the fabric and flat-lined it with muslin. The eyelets in back were painted black.
