A lapel is a folded flap of cloth on the front of a jacket or coat below the collar. It is most commonly found on formal clothing and suit jackets. Usually, it is formed by folding over the front edge of the jacket or coat and sewing it to the collar. There are three basic forms of lapel: notched, peaked, and shawl. The notched lapel is the most common and is usually seen on business suits and on more casual jackets like blazers and sport coats. The peaked lapel is more formal and nearly always used on double-breasted jackets, but also frequently appears on single-breasted ones. The shawl lapel is usually carried by tuxedos and mess jackets. Lapels are typically triangular, although there are different lapel styles to choose from. Lapels are purely for aesthetics and do not serve a practical function. They are a key component of the art and sculpture of tailoring, helping create the shape and physique you want through clever design. Lapels can be used to elongate and slim your torso, while the placement of the lines and angles also accentuates your shoulders. Lapel pins are accessories that sit on the lapel of a suit jacket and serve a purely aesthetic function. They are worn to make you look more stylish and handsome.
