darts means: A dressmaker’s punctuation mark is the dart. These are used to shape garments by bending straight fabrics towards the body. To create darts, you need to stitch a thin, long pinch that is flattened to a point. Then, press down on one side. You can adjust the width or length of the darts to fit your garment. They are tapered either at one end, or both. (in Fashion Dictionary)
