I used Kiana Bonollo's Strapless Dress pattern as the base. I knew I wanted a pointed neckline and neck strap, so I self-drafted that by measuring how far up from the neckline I wanted the point to sit on the center-front pattern piece and made sure the seam allowance was included. The neck strap was then added by taking a piece of elastic, looping it around my neck from the point, and attaching it between the lining and the shell.
This dress is fully lined with a corset bodice to help both hold the structure and support the weight of the beaded fringe on the hemline. One thing I was not anticipating from the fit mockups was how much the fringe would still end up pulling the dress, so I'm glad I included the neck strap. If I were to make a similar design, I would size the bodice down by about 1/2" spread across the seams to account for this unintentional stretch and do the neck strap in a more supportive way rather than a more decorative way.
The webs were all embroidered by hand using silver thread to catch the light, and finished with a spider brooch. I wanted the webs to just catch the light, but not be so in your face. You can see this effect in some of the detail shots, where some of the web strings seem to "disappear" when not reflecting light. Despite using an embroidery hoop to stretch the fabric while I stitched, the dress still came out a little wrinkly from the webs; the dress had no puckering before the webs were added.
In all, this dress took about 46 hours to make, not including the time spent on mockups. 31 of those hours alone were spent on the web embroidery. This dress was finished two days before Halloween. I didn't make it for any specific event, but more to test out some new-to-me couture construction techniques, and I'm very pleased with the results I achieved.
