To grade a pattern means to manipulate an existing pattern at various points in order to make it fit a smaller or larger size. Each pattern piece has several vertical and horizontal lines in areas where the body generally gets bigger or smaller, as the sizes change. For a bodice, they are illustrated above:

A-B: Front/Back neckline to waist

C-D Shoulder to waist

E-F Armhole to waist

G-H Center Front/Center Back to armhole

I-J Center Front/Center Back to side seam

(Above is a bodice front. The same lines are valid for a bodice back. ) The vertical lines should be parallel to the CF or CB, and the horizontal lines should be perpendicular to the CF of CB.

**Make sure your pattern is WITHOUT seam allowance. If it has seam allowance, remove it.**

    How do you know where to put the AB and CD lines? How far from CF, for example. Are there set measurements to use , I’m grading a 44" but to a 54", would the amount of CF to line AB be the same on every bodice pattern?

    what do you mean by The vertical lines should be parallel to CF or CB? do you mean to say CD or AB? Line CF or CB would be diagonal vertical lines….meaning all vertical lines would be tilted(at diagonal angle??) …could you please clarify?Thank you for your post. I really need to understand how to do this so your reply would be so greatly appreciated
