A Balloon Skirt is a skirt with a hem that is gathered inward, creating a rounded and voluminous silhouette. It is characterized by its sculptural shape and sense of volume. Common elements include tucked or lined hems that form the balloon shape, high-waisted or mid-waisted designs, structured fabrics such as taffeta, cotton, or blended materials, and simple or decorative details. The overall style emphasizes dimensionality, playfulness, and bold fashion presence.
