My baby Sofie graduated from high school recently and I made her a new dress for her Valedictory dinner. I anticipated this event a while back and bought some silk chiffon from China on my last Hong Kong visit. The fabric is an ombra that is black on both selvages and grading to white/cream in the middle. Luckily she was happy with the fabric.
Butterick 5029 for the front bodice. I then cut long ties - very long rectangles and attached them just under the bust. To keep things simple I used elastic across the back to keep the dress close to the body as per the nightgown pattern - so no zip or other fastener needed! I later went back and added elastic under the bust too to keep that area also closer to the body
