This is a drawing of a sewing pattern. The drawing showcases various segments of a garment pattern, likely for tailoring a specific design. The pattern is meticulously outlined with precise lines and annotations, indicating different sections and instructions for assembly. On the top left, there are smaller sections that likely correspond to shoulder and sleeve elements, accompanied by measurement markings. Below, there are three elongated shapes marked as D, D-1, and D-2, which seem to relate to the main body of the garment, with further line divisions and notes that suggest dimensions and possibly folding or cutting lines. The entire composition is rendered in clear, technical lines, typical of patterns used in dressmaking to ensure accuracy and proper fit.
