You can generate your own bodice pattern using GINANI Bodice Pattern Macro. The macro gives you perfectly fitting bodice patterns for as many adult females as you want. Ensure your measurements are correct.
Basic blocks are foundation patterns for fitting and the creation of designs. If your basic pattern is created from accurate measurements, the designs that are created from it will also have the same fit. Having good basic blocks will make a fashion designer’s job much easier and more profitable.
