Jen Eugley. It's worn by the lovely Elizabeth Swann sculpt Tonner Doll, a former Abandoned Bride, inspired by actress Keira Knightley, from the Pirates of the Caribbean line. I just love how it turned out.
A few details about the gown--it's crafted from silk dupioni and edged in antique ivory lace. The bodice snaps in the front and is lined in white to prevent staining. The skirt is a single piece that snaps at the waist, and its underskirt is attached and cut in almost a full circle. Jen crafted a pannier for historical accuracy and to create the foundation shape for the drape of the skirt as well. This was made from boning and snaps separately over the dolls hips.
You can see the original inspiration piece online under Costumes, called the Drunken Dress. I'd still like to create a cameo necklace, similar to the one shown there, in addition to a small white rose decoration, and Georgiana still needs some shoes. But I'm really pleased with how she's turned out so far.
