Jacket lapels are the folded flaps of cloth on the front of a jacket or coat, and are most commonly found on formal clothing and suit jackets. Usually they are formed by folding over the front edges of the jacket or coat and sewing them to the collar, an extra piece of fabric around the back of the neck, as shown in the image.
There are three basic forms of lapels: notched, peaked and shawl. Notched lapels, the most common, are usually seen on business suits.Peaked lapels are more formal, and nearly always used on double breasted jackets or coats.Shawl lapels are usually carried by dinner jackets.
