People having a heart-shaped face should choose sunglasses that are of more delicate styles, such as wire or oversize plastic frames that will not draw attention to the forehead. Glasses with bottom-heavy frames that add width to lower face or narrow, round frames that soften the forehead will also flatter you. You are also required to choose styles with low-set temples to draw attention to downward. Do remember to avoid Top-heavy styles that draw attention upward and decorative temples that accentuate the broad upper face. There are some famous stars with heart shaped face like Jennifer Aniston, Halle Barry, David Spade. You may refer to their choice of sunglasses.
