Finally, a photo to share!
Pattern: Vogue 8475: “Close-fitting across bust, lined, empire dress with partial cut-out in back, gathered bodice front and skirt, shoulder straps and side zipper closing.”
Fabric: crepe back satin from JoAnn ETC
Modifications: Replaced cut-out with a full back. Modified the bodice to raise the v-line of the neck. It would’ve been cut as low as the black piece.
Critique: My daughter was pleased with it, but I was not happy with the bustline. I tightened it up a bit, but I should have moved the straps in bit more to keep the top from gaping. (I am working on my alteration skills.) The crepe back satin was heavy and has no give like natural fibers, so a bit difficult to sew.
Prom: Fun!
