Heart faces are widest at the forehead and narrow toward the chin, often with a pointed jawline. The goal is to soften the upper face and add subtle width at the chin — look for frames like round, oval, or light cat-eye styles with a bottom-heavy or rimless design. Avoid heavily embellished or top-heavy frames, which can overemphasize the forehead.
