A waist-length jacket is a type of outerwear that typically falls just above the waistline. An Eton is a type of waist-length jacket with a narrow collar and lapels, usually made of wool or tweed. A BOLERO is a short, waist-length jacket with a round neckline and no lapels, often made of velvet or lace. Both styles of waist-length jackets are popular for formal occasions such as weddings and other special events.
