- accordion-pleat [uh-kawr-dee-uhn]-[pleet]
- Narrow, evenly spaced vertical folds pressed (or heat-set) into fabric, forming alternating raised and recessed ridges. Pleat widths are usually widest at the bottom and gradually become narrow towards the top, creating a flared shape. The pleat shapes form a zig-zag pattern along the fabric edges when expanded. Also called sunburst pleats, or fan pleats.
