A Bubble Skirt is a skirt with a hem gathered inward to create a rounded, puffy silhouette, characterized by its airy volume and sculptural form. Common elements include tucked-in hems, curved voluminous shapes, high-waisted or mid-waisted designs, lightweight or structured fabrics such as chiffon, taffeta, or cotton, and simple or playful styles. The overall look emphasizes playfulness, liveliness, and lightness, creating a sweet and fashionable appearance.
