A sweetheart neckline is a popular design feature in women's clothing, particularly in dresses and tops. It is characterized by a curved shape that resembles the top of a heart, creating a flattering and feminine silhouette. This neckline typically dips in the center and rises at the shoulders, enhancing the bust area and adding a romantic touch to the garment. Commonly found in formal wear, such as wedding dresses and evening gowns, the sweetheart neckline can be styled in various ways. It can be paired with different sleeve types, from strapless to capped sleeves, making it versatile for various occasions and body types.
