Drafting a Back Bodice Sloper
Using the measurements taken from the dress form, the back bodice sloper is drawn according to the following diagram. The drawing to fit the BJD will be made, step-by-step. There are about 31 steps to drafting the back bodice sloper, in Modern Pattern Design by Harriet Pepin (1942).

Read each step carefully!
12. C-9 -- From point C, measure off a line equal to the Shoulder Height Measurement, less the 4 inches just used to locate point C, to a point somewhere on line 5. Label 9.
13. 9-10 -- From point 9, measure upward along the guide line 5 a distance equal to the Side Bodice Length. Label this point 10.
14. 10-D -- From point 10, square a line which will intersect with guide line 4. Mark the intersection point D.
15. B-E -- From point B, measure upward on line B-A a distance equal to Shoulder Blade Height. (This is measurement number 12 which corresponds to bust height taken for front.) Mark point E.
16. E-F -- Square a line from point E equal to one-half the Shoulder Blade Width. (This is measurement number 13 which corresponds to bust point width in front.) Label point F.
