Gwyneth Paltrow and Hilary Swank both have the broad forehead, chiseled jawline and wide chin and lengthy face of the classic long square shape. This shape looks best with sunglasses that act as an opposing force.

QUIZ: What’s Your Face Shape?

“The goal is to soften and balance a strong jawline,” says Kristie Whitford, spokesperson for the Vision Council, and organization that represents manufacturers and suppliers in the optical industry.

Go for circular, oval or curved frames that serve as geometric contrast to the square shape of the jawline. Cat-eye sunglasses can also work, since they sit up higher on the face, which also acts to balance the bottom of the face.

And feel free to bling-out with sparkling embellishments at the temples, which help create the illusion of a wider top half.

Square, rectangular and otherwise boxy frames are all shapes you can do without, since they will just make your face look more square.

Here are the best frames for round heart-shaped faces:

* Round and embellished-shaped sunglasses, such as Dolce & Gabbana filigree 51MM round sunglasses, $390.

* Round-shaped sunglasses, such as Chloé eria 56MM round sunglasses.

* Vintage-looking cat-eye style sunglasses, such as Salvatore Ferragamo Color Block Cat Eye Sunglasses.
