I once made Barbie a "designer jumpsuit" (early eighties) out of some stretchy first aid gauze. Looked pretty hot too.
Then I had a an old damask dinner napkin from somewhere (you never know at my house) I cut a hole in the center, slid Barbie down into it and tied the waist with a red hair ribbon. Very easy strapless "cocktail" dress. (But that's just trivia.)
