Drafting the Foundational Bra Block

Draft a custom-fit bra band pattern from body measurements, incorporating negative ease calculations.

Draft a two-part vertical seam cup pattern that aligns with the breast apex and desired projection.

Draft the connecting bridge (gore) pattern, adjusting its height and width for different levels of breast separation.

True the pattern pieces to ensure all seams are of equal length and will sew together correctly.

Add seam allowances and markings (notches, grainlines, apex) to the finalized block pattern.
