A lot of factors has to be put into consideration when choosing your sunglasses, one of which is the shape of your face. The shape of your face will determine the right kind of sunglasses that will suit it, therefore you need to find out what the shape of your face is.
The four basic face shapes are round, oval, heart and square shape. You can determine which of these shapes your face is by facing the mirror and using your lipstick to trace the outline of your face on the mirror.
The right kind of sunglasses for a round face should not have curved features but should emphasize the sharp angular lines that will elongate the face. Square or rectangular sunglasses are best for round face shapes.
People with square face have a broad forehead and a strong jaw line. They should therefore wear sunglasses with round or oval shape or cat eye styles as this will accentuate the sharpness of their features.
Heart face shape is characterized by a wide forehead and a narrow chin. The ideal sunglasses for this type of face shape are cat eye styles and rounded rectangular styles.
Oval face shape is gently rounded with even features. With an oval face shape, you can pretty much wear any shape of sunglasses you fancy as all kinds of shapes of sunglasses look good on it.
Do not wear big frames though, just get sunglasses that cover your face from your eyebrow to your cheekbones.
