Fit & patternmaking

The process of constructing a trouser pattern from waist, hip, crotch, and leg measurements, shaping the crotch curve, inseam, and outseam of the front and back leg pieces.

The pattern pieces and construction lines for a trouser's front closure, including the fly extension, fly shield, and zipper placement, added to the basic trouser front.

The process of separating a back-waist design line from a trouser block to create a yoke pattern piece, often absorbing the waist dart into its seam.
