An A-line silhouette in fashion refers to a garment that is fitted at the hips and gradually widens towards the hem, giving the impression of the letter ‘A’. Common in skirts and dresses, the A-line shape is flattering for most body types as it balances the figure and camouflages wider hips. The simplicity of its structure allows for versatility in length, fabric, and occasion, making A-line garments a staple in both casual and formal wardrobes. Originating in the 1950s, the term was first used by the French couture designer Christian Dior as the label for his spring collection in 1955. The A-line style remains popular due to its timeless elegance and ability to adapt to various fashion trends and body shapes.
