From O go down to C one-quarter of the breast, which is 9 inches, and draw a line across. Draw a line from O over to K at right angles with the back-line.
In the middle, between O and C, fix a point marked B and draw a line over to N. From C to G is one-third breast and 1 inch, equal to 7 inches, and draw a line at right angles with line C-G. From G to H is one-fourth breast, equal to 4½ inches, there draw a line at right angles with the one under arm.
From 1, centre of back, to J, at the front of the breast, place one-half of the breast-measure, equal to 18 inches, and at J draw a right angle line up and down like line K-J and S. From O to 13 is 2 inches.
From N to 13 draw a line, and then, commencing at 13, curve the shoulder, letting it rise above the last line one-half inch to 14.
Starting three-fourths inch inside of line G begin to curve the arm-hole past 12 to 17 and H. In the middle, between N and G, fix the point to start seams from for the back. Draw line from thence past 19 to 2 and 29—this makes the back with narrow shoulders.
To draw the first side-body place from 2 to 3 one inch, curve the line from 19 to 3, gradually beginning to separate below 19 without curving too much, care being taken to get a neat curve. Below 3 curve toward the back till at hip, 21, it will meet the back, and thence downwards, till at the bottom it will over-lap the back 1 inch to 30.
Make the width of side-body at the top any distance desired, say 3 inches, and make it the same at waist, or from 3 to 4, 3 inches. Then curve from 17 to 4.
Lay a long straight-edge, closing at 17, and three-fourths inch from point 4; while in this position mark a line along it from the hip-line downward, and connect it by a curve from 4 to 24.
Go in from 4 to 5 a distance of three-fourths inch, and curve from 17 to 5, but be careful to commence to separate side-body only 1½ inch below 17. Lay a straight-edge, as before, at 17, and three-fourths inch from 5, so that it will lay towards front, then from hip downwards draw a line to the bottom and finish by curving from 5 to meet this at hip, 23.
From 17 to 18 may be only 1½ or 2 inches, according to the size—2 inches will be sufficient for a 36 breast.
