Create your own bustier base pattern with this technical file made easier by clear and precise instructions. Each step is detailed and accompanied by explicit sketches; leading to a full understanding of the working method and a top-of-the-range quality product in the predefined size of your choice. Starting with the bodice base pattern, it is possible to construct a bustier base pattern with shoulder strap seams (vertical seams on the front and back of the bustier). This classical bustier follows the curves of the future wearer. From this base, other transformations are possible.
