A Bell Sleeve is a sleeve style that flares dramatically outward from the wrist, creating a bell-like silhouette characterized by flowing movement and vintage-inspired decoration. Common elements include fitted upper sleeves, flared cuffs, chiffon, lace, or soft draping fabrics, and frequent use in dresses, blouses, and bohemian-inspired garments. The overall style emphasizes romance, elegance, and theatrical movement, creating a soft and visually flowing appearance.
