Lapels are the folded flaps of fabric on the front of a jacket or coat, typically found in formal wear like suits and blazers. They are an important design element that can vary in style, such as notched, peaked, or shawl lapels, each giving a different look to the garment. In addition to their aesthetic appeal, lapels can also serve practical purposes, such as providing structure to the jacket and allowing for the attachment of accessories like pins or boutonnieres. The width and shape of lapels can influence the overall silhouette and style of the outfit, making them a key feature in fashion design.
