You have a heart face if you have a wider forehead and narrow/compact jaw line and chin and high cheekbones.
Best Frames: Go for round edged sunglasses that accentuate your face shape the best and add width to the lower part of your face. Also, a rectangular frame can soften your pointed chin.
Frames not for you: Better you keep away from those frames that sit high and wide on your face only to highlight your already wide forehead.
