The sweetheart neckline has a bow above each breast so that it looks like the upper side of a heart. Wedding dresses with a sweetheart neckline make a beautiful décolleté and the popularity of this kind of neckline has good reasons. The sweetheart neckline flatters every figure and suits nearly every woman - no matter if slender or full-bodied. This neckline emphasizes womanly curves, stretches visually and sets the décolleté into the right light. In its strapless variation the sweetheart neckline is the most popular neckline for wedding dresses.
