What is a sweetheart neckline?

A sweetheart neckline is a style of neckline that is shaped like the top of a heart or half of a heart. It is commonly seen on dresses and tops and is considered to be a feminine and romantic style. The neckline typically dips in the center to create the heart shape, with the edges curving upwards towards the shoulders. Sweetheart necklines are flattering for a variety of body types and can be found on both casual and formal garments. This style is often used in wedding dresses, prom dresses, and evening gowns to create a flattering and elegant look.
