The sweetheart neckline has become a Genealogy favorite and sought after by many girls! This shape shows off your shoulders and neck and compliments most bust lines. The sweetheart neckline gets its name from the cut and shape of the neckline design. The soft cut in the center of the bust gives the design a more graceful curve than the plunging neckline or a neckline that is cut straight across. The result is a beautiful heart shape above the bust that provides modest coverage, yet still drawing attention to the bust. The sweetheart neckline may not be the best option for the bustier girl, but works great on small to medium bust sizes. A busty girl may be better off in a halter or neckline that is cut straight across to give a bit more coverage on top. We see the sweetheart neckline featured on many wedding gowns and prom dresses and this cut will continue to be very popular. While this neckline has come and gone in casual wear, it remains a favorite in formal wear.
