A nightgown pattern may be developed from the shirt waist pattern in the same manner as suggested for the chemise, except that the nightgown is made long enough to touch the floor. When the length is laid out on the center front a line is drawn perpendicular to it at the bottom and one-fourth the desired width of the nightgown is measured out on this line. This point is connected with the top of the under-arm seam of the waist. The back of the nightgown is laid out in the same manner.
