Princess seams
（重定向自Princess seam）
Princess seams are long rounded seams sewn into women's blouses or shirts to add shaping or a tailored fit to closely follow a woman's shape. They are sewn into the front and/or back of a shirt, and extend from the waist up to the arms. Princess seams are distinct from darts in that they form a continuous line and are a full seam. Darts, on the other hand, are folds sewn into the clothing to shape the resultant garment.
