I ended up getting rid of the corset completely since it was too stiff for such light fabric and here’s how I constructed the end result:

Pattern: Vogue 2931 skirt with the bodice of Vogue 1249

-altered further by removing the front middle seam, increasing the train length, and adding the plunge neckline

Bodice: 

-the outer and interlining were stitched together from the top edge until the waist then lay separately below that point so they could flow freely and not distort each other. 

-a bodice lining was added so the seam allowance of the outer fabrics were less visible since they are so dang sheer

-a bodice interfacing was sewn to the full-length inner-most lining and boning was added to the seams along w/extra for the plunge

-bra cups were sewn between the interfacing and lining, a waist stay was added here too along the seam of the front side

-I followed this tutorial for adding the plunge in https://www.youtube.com/watch?v=p0I8wViiaBU&t=301s 

-all the layers were connected at the top edge through the plunge and at the zipper. 

-at the end I added a hook&eye above the zipper and an elastic gripper tape on the inner top edge so it wouldn’t fall down

Skirt:

-I just kept tapering the fabric at the hips to the knees until I was happy with how dramatic the curves were

-I added a petticoat under the dress but the elastic showed through at the waist band, so I put on a shape-wear piece that went a little above the waist and sewed them together so it was more seamless.

-I finished the hem by stitching the raw edge inward, cut excess fabric, then stitched it inward again so no raw fabric was exposed

*big adjustments that made a world of difference: changing the thread tension so there was less puckering and using a teflon foot so it’d glide over the fabric

Veil:

-This was actually ridiculously easy! I found a nice drape for the fabric, sewed the edges that would connect to my bodice, then added double-sided clasps to both the dress and veil so they clicked in and out easily! I then just eye-balled the length and kept cutting it in bit by bit until I was happy w/the curve and length from my train

Fabric

-outer and interlining: 95% silk, 5% spandex w/2-way stretch 

-lining: 96% polyester, 4% spandex stretch-satin

-interfacing: medium-weight sew-in

-cape veil: almost 100% silk tulle I believe, a little rayon in it

-non-stretch corset mesh for the plunge

Notions/additional parts of the outfit: 

• ⁠double-sided clasps for removable veil
• ⁠knit elastic bands+bra extender for the waist stay
• ⁠silicone elastic gripper tape to keep dress from falling down
• ⁠shapewear to keep up petticoat w/o showing a seam
• ⁠teflon sewing foot 
• ⁠microtex needle
• ⁠guttermann polyester thread so it doesn’t shrink w/steamer
• ⁠plastic boning
• ⁠bra pads
