Draping Period Costumes
7. Drape the rest of the shoulder seam; add one-quarter inch of ease. Because the silhouette is so very fitted for such a long distance, it is necessary to drape a dart on the SB piece. Begin the dart at the armhole
about halfway between the shoulder seam and the side seam. Curve it in toward the back, like a princess seam, and back out toward the side seam as you extend past the hip. 8. Finish draping the armhole. Drape the side seam to fit the torso. Once you reach the widest part of the hip, curve the side seam onto the SOG.
