Will you smack me with a really big stick if I say it sounds like a deconstruction/reconstruction project? I can visualize the amazing trim... but I also know you a bit, dear heart, and know that you'll be annoyed with interior scrunchies.
As for what to wear in fine situations that has good coverage... I think you'd look lovely and elegant in a "dinner dress"--something with a pretty, semi-elaborate to elaborately-trimmed open sleeve, good undersleeves, and I'd look at a "fashion forward" slightly funneled-up high neckline with a standing white frill there. You'd have full scar coverage, but REALLY elegant fashion, and could dance if you chose to do so.
Even silk wrinkles that SEEM Immortal can usually be salvaged with a good damp pressing. After hand-application of elaborate trim, lay the whole thing trim-side down on a nice fluffy towel, and give it another light damp press, and you can remove the small wrinkles that result from the handwork. Following period recommendations on "how to arrange one's work" also minimizes the hand contact while applying such things, which makes for an overall better result.
