When you are thinking about choosing earrings to flatter your face shape, think about how to balance it.
How to Choose Earrings to Flatter a Heart Shape Face
A heart shape face has a wider forehead and then narrows down to a more pointed V shape jaw.
Thus the earrings that flatter will widen as towards the bottom, and be narrower at the top.
A drop earring is more flattering than a stud, particularly a wider stud that will make the middle of your face wider, but add no balance to your jaw area.
Anything too narrow at the jaw won’t add balance. Anything too wide at the cheeks will add breadth that isn’t necessary. Instead look for shapes that widen as they drop.
