There is something so fun about discovering sewing terms and how they resonate with fashion. The sweetheart neckline is a shape we’ve all seen before. Maybe it was on our prom dress, maybe in a New Year’s Eve ensemble. The sweetheart neckline gets its name for resembling the curves at the top of a heart. It’s also a particularly flattering detail that accentuates and frames not only a woman’s decolletage but the also the much admired collarbone. Come wedding or awards season, it’s the fastest way to get pulses racing.
