Make the bottom of the back 1½ inches wide. This is only a medium, as it can be made 1 inch or 2 inches, which only places the seam either further back or more to the front. Then from R draw a straight line to 1½ and slightly curve a line drawn to 19 and to 2. Between 19 and 2 curve more towards centre of back. A few trials will enable you to make a nice shaped curve.
Fig. 4.
From 2 on back to side body at 1 is 1 inch, and curve from 19 to 1.
From V, straight down, draw a line to 4 and curve a trifle on either side of it, also separate side-body from X to 3. Point X is midway between line R and V and the distance between 3 and 4 is about ½ inch more than X to V.
Take ⅙ of the breast, equal to 3 inches, and place it from point N to P and use point N as a pivot and sweep from P to 15.
At a point on waist-line directly under H, measure up past P, shoulder point, the front length, which is in our measure 18½, deducting the width of top of back, and wherever it reaches to is point P. This may, sometimes, when the person is erect, reach above the line; and again, on hollow or stooping shoulders, be below it. Wherever it reaches is the shoulder point, and when it goes above we sweep at a point above N even with shoulder for neck, and of course, should it be below the line, at a point below N, so that the neck will keep its shape to harmonize with the height of shoulder point.
Wherever point P is located by measure, above or below, or on the line, start to draw the line to B, on back, for height of shoulder, and place the width of back shoulder from A to G on this line from P to get point 17. Then from 17 curve above it about one-quarter inch to P, and also draw the arm-hole, going inside of line H, but never over one-half inch, to V, as shown on the diagram. Drop a trifle from 17 to 20.
