The basic block
The straight skirt block is drafted from waist, hip, hip depth (waist to hip line) and length. The difference between waist and hip is shared between darts and side seams.
From pencil to circle: learn the shapes, understand how each pattern is built, then order the steps for drafting a basic skirt block.
A helpful tip: every skirt shape starts from the basic straight skirt block, then changes by slashing, spreading and closing.
The straight skirt block is drafted from waist, hip, hip depth (waist to hip line) and length. The difference between waist and hip is shared between darts and side seams.
Usually made by closing all or part of the waist dart so the hem opens out. Christian Dior presented his "A-line" in spring 1955.
For a full circle: waist radius = waist ÷ (2 × π). For a half circle: waist ÷ π. Let it hang for a day before levelling the hem, because the bias sections drop.
Made of vertical panels (4, 6, 8 or more), each narrow at the waist and widening to the hem, so it fits closely and flares below.
Narrow and straight or slightly tapered to the knee, so it needs a back vent or kick pleat for walking.
A triangular or sector-shaped piece set into a seam or slash to add flare at the hem, as in a mermaid skirt.
