What are the characteristics of a Heart shaped face?

If your face shape is similar to a round face, but your jawline is narrower, your face might be heart-shaped. People with heart shaped faces, have wider foreheads and narrower chins. Their face is usually shorter (not long) and the cheekbones are often higher.

Celebrities with Heart shaped faces include Reese Witherspoon, Halle Berry, Julia Roberts, Naomi Campbell, Taylor Lautner, and Ryan Gosling

What eyeglasses and sunglasses features look best with a Heart face shape?

Choose a frame that is a little wider than your forehead to emphasize your higher cheekbones. A bottom heavy frame will add bulk to the bottom of your face to balance it. 

A light colored frame or rimless frame is great if you want the eyeglasses to be less noticeable and leave your face to speak for itself.
