How It Works

Darts remove fabric to create shape, fitting flat fabric to body curves. Bust darts point toward the bust apex but should stop 1 inch before it. Waist darts distribute the bust-waist difference: typically 25% in front darts, 35% in back darts, and the remainder in side seams. Wider darts create more shape but can look bulky if over 1.5 inches wide.
