A pleat is a fold of fabric pressed or sewn into place. It adds volume, movement, and structure. Pleats appear on skirts, trousers, dresses, and shirts. They can be sharp and permanent or soft and flowing. The direction and width of the fold change how the garment moves. A pleated skirt swings differently from a flat one.

Types are many. The knife pleat is a simple fold pressed to one side. The box pleat has two folds facing outward, often used at the back of a shirt. The accordion pleat is narrow and evenly spaced, like the folds of a paper fan. The inverted pleat has two folds facing inward. The sunburst pleat radiates from a single point. The crystal pleat is very fine and often used on formal wear. Each type creates a different rhythm.

Pleats require precise work. The fabric must be measured, folded, and set with heat or stitching. Synthetic fabrics hold pleats well because heat sets the shape permanently. Natural fibers like wool and cotton may need stitching to maintain the fold. Over time, pleats can relax, especially with washing. Care instructions matter. Many pleated garments should be dry cleaned or steamed rather than washed. Ironing can flatten the fold and ruin the effect. A well-made pleat holds its line for years.
