I used the pattern pieces from Burda Strapless Jumpsuit however I didn’t follow the instructions and made it my own (Quelle surprise!?).
My Singer 347 is in the shop so I’m using my Singer Featherweight (no zigzag stitching). To compensate I used an elastic bobbin thread for anything sewn vertically. I also used a 1″ elastic for the waist and 1″ for the top of the bustier.
