Yup - pleating stretch silk charmeuse appears to be a no-go. I THINK it's the "stretch" part that does it in. I still plan on trying this out someday with real silk charmeuse. I do like the full gown version in some ways a bit better than the 2-piece.
Bubbles, bubbles, everywhere. It's ALMOST homogeneous enough that it is wearable, but I think not quite. It does look pretty with a belt on, though! Perhaps I just now have the world's most luxurious nightgown? (that I can't wash?)
