(Also how to rotate bust dart OUT at sideseam)
Size Medium traced, then slashed (in red) and spread using the Fit For Real People method for non-darted bodices.
After FBA is complete, trace the sideseam onto new tissue below.
Close the horizontal bust dart by rotating pattern, while over sideseam tracing on under layer.
New adjusted pattern is shown in red. Horizontal bust dart has been moved to the side seam and excess dart uptake is cut off.
Final pattern as retraced, with markings, etc. The "bump out" at the bust area sideseam will be eased to the back piece. I also curved up the bottom hem area a bit to compensate for the added length from the FBA.
