Ruching is a type of decorative FRILL or pleating that is often used in clothing and other fabric items. It is created by gathering fabric into small pleats or folds, which can be secured with stitching or elastic. Ruching is often used to add texture and visual interest to garments, as well as to create a more fitted look. It is also used to create volume and fullness in skirts, dresses, and other garments.
