Lapel - la-pel - A part of the coat folded back which continues on from the collar. There are three basic forms of lapels: notched, peaked and shawl. Notched are your common everyday lapels found on suits. Peaked lapels are more formal, and nearly always used on double breasted jackets or coats, the point at the shoulders. Shawl is usually found on dinner jackets and is rounded with no points or strong angles.
