Why are the gores cut out in a triangle shape and sewn together across the fabric?

The triangular shape of the gores allows for a more efficient use of fabric, reducing waste while providing the necessary shape and structure to the garment. This design promotes better fit and movement, especially in areas like skirts or sleeves, where curvature is needed. By sewing the triangular gores together, the garment can achieve a more tailored and flattering silhouette, enhancing both comfort and style.
