Drafting a Front Bodice Sloper
Using the measurements taken from the dress form, the front bodice sloper is drawn according to the following diagram. The drawing to fit the BJD will be made, step-by-step. There are about 26 steps to drafting the front bodice sloper, in Modern Pattern Design by Harriet Pepin (1942).

Read each step carefully!
1. A — Point A is located 4 inches below the top edge of your paper and 1 inch inward from the right margin. Place a dot and label point A.
2. A-B — Line A-B is equal in length to the amount of the Center Bodice Length given in measurement chart. Starting with point A, measure downward that distance, keeping square parallel to right edge of the paper. Place dot and label point B. Connect A and B.
3. B-2 — This line equals Full Bodice Length measurement on the chart. Lay square along line A-B with short arm downward pointing to the left and the long arm extending upward, falling upon points B and A. From point B, measure off a distance equal to the Full Bodice Length and mark dot. Label dot 2. Draw the extending line A-2.
4. Draw a guide line 15 inches long upon which points 3, 4 and 5 will be located. As this line must be at a right angle (squared) from the vertical line B-2, lay the square so that the short arm extends downward along the line B-2 and the long arm extends across the paper towards the left.
5. 2-3 — From point 2, measure off a distance equal to one-half your Across Measurement. Label that point 3.
