The tailored jacket with shoulder strap seams and a side piece (5 pieces) can be made using this technical file. Its precise written explanations and detailed sketches will bring you a full understanding of the method to follow for a top-of-the-range result in the size of your choice. The shoulder strap seams go from the shoulder down to the garment hem, separating the front and back into two pieces. This model also has a side piece. The simplest way to approach this new base is to start from the tailored jacket base pattern with three pieces and proceed to make five pieces for the new model: front, back, side front panel, side back panel and side piece. This new base will allow you to make many other models of tailored jacket and coat. Several other technical files correspond to it perfectly: The technical file of the tailored sleeve base pattern The technical file of the puffed sleeve The technical file of the tailored collar The technical file of the shawl collar.
