In bridal fashion, a sleeve that flares dramatically from the elbow or upper arm is a bell sleeve.
Bell sleeves are narrow at the shoulder or upper arm and widen toward the wrist, creating a shape that resembles a bell. The flare may begin at the elbow, forearm, or even higher on the arm. Bridal designers use the style to add movement and a distinctly romantic or bohemian character.
The shape has appeared repeatedly in Western fashion, including clothing influenced by medieval, Renaissance, Victorian, and 1960s styles. Modern wedding gowns may combine bell sleeves with lace, transparent tulle, or simple crepe.
A bell sleeve differs from a bishop sleeve, which is generally full through its length and gathered into a cuff. A trumpet sleeve also flares, but the term is often used for a more close-fitting sleeve that widens mainly near the wrist.
