Using this technical file, learn how to make a tailored jacket base pattern (3 pieces) with a shoulder dart pivot. Its clear explanations and detailed sketches demonstrate the method to follow step by step for a full understanding of the model undertaken and the shoulder dart pivot for a top-of-the-range result in the size and fabric of your choice. The shoulder dart is shifted (by pivot) in this model to create a bust dart. In this example, the back and side piece do not change. This new base can be transformed in different ways and can be adapted to the tailored sleeve and collar.
