Since its inception in the early 20th century, the cocoon silhouette has never left the fashion scene. Its prototype has been refined by designers repeatedly, and it has graced the stage time over the past few decades. At the 2023 autumn/winter season, the cocoon silhouette became a prominent element under the spotlight. This time, the designers collectively played with exaggerated sleeve shapes; sleeves cascade down from the shoulder line, emphasizing the volume and highlighting the presence of the garment while softening the lines of the body itself. This distinct feature imbues the cocoon silhouette with narrative potential. Today, we understand why it never goes out of style: it represents the rounded and full-bodied traits of femininity, often interpreted as a design seeking security and evoking a protective instinct. However, the outward extension of volume is not merely a gentle probe: when this silhouette combines with stiff fabrics, a sense of dominance emerges irresistibly.
