Face shapes play a huge role in which eyeglass frames will look attractive on you. To determine your face shape and which eyeglass styles will look best, pull your hair away from your face and look directly into a mirror. Take a close look at the overall shape and contours of your face and head.

Here are the seven primary face shapes and the type of eyeglass frames that look best on each shape:

Oval face shape

An oval face shape is considered to be ideal because of its balanced proportions.

To maintain the natural balance of an oval face shape, look for eyeglass frames that are as wide as (or wider than) the broadest part of your face.

Walnut-shaped frames that are not too deep or narrow are a very good choice.

Heart-shaped face

A heart-shaped face has a wide top third and a narrow bottom third.

To reduce the apparent width of the top of the face, choose frame shapes that are wider at the bottom. Thin, light-colored frames and rimless frames that have a light, airy appearance also are good choices.

Oblong face shape

An oblong face shape is longer than it is wide and has a long, straight cheek line.

To make an oblong face appear shorter and more balanced, try frames that have more depth than width.

Frames with decorative or contrasting temples also add width to the face.

Square face shape

A square face shape has a strong jaw and a broad forehead, and the width and length of the face have roughly the same proportions.

To make a square face look longer and soften its angles, try narrow frame styles, frames that have more width than depth, and narrow ovals.

Diamond face shape

Diamond-shaped faces are narrow at the forehead and jawline, and have broad cheekbones that may be high and dramatic. This is the rarest face shape.

To highlight the eyes and soften the cheekbones, try frames that have detailing or distinctive brow lines. Rimless eyeglasses and frames with oval or cat-eye shapes also can be good choices.

Round face shape

A round face shape has curved lines with the width and length in the same proportions and no angles.

To make a round face appear thinner and longer, try angular narrow eyeglass frames to lengthen the face.

Wide rectangular frames also can be a good choice.

Base-down triangle

A base-down triangular face shape has a narrow forehead and widens at the cheek and chin areas.

To add width and emphasize the narrow upper third of the face, try frames that are heavily accented with color and detailing on the top half (brow) of the frame.

Frames with cat-eye shapes also look good on a base-down triangle face shape.

When choosing eyeglasses, face shape isn't the only factor that determines which frames will look best on you — your skin tone, eye color and hair color also play important roles.

The best eyeglasses will complement the coloration of your face, eyes and hair.

Skin tone

Regardless of the color of your skin, skin tones are categorized as either "cool" or "warm."

A cool complexion has blue or pink undertones, and a warm complexion has a "peaches and cream" or yellow cast. Olive skin is considered cool because it is a mixture of blue and yellow.

Eye color

Eye colors usually are a secondary element in determining your coloring because of the many variations of eye color.

For example, blue eyes can range from a cool almost-violet to a pale blue-gray, which is warm. Brown eyes can vary from a light cider shade (warm) through a medium-brown to a cool almost-black.

Hair color

Hair colors also are considered warm or cool.

"Cool" colors include:

• Strawberry blond
• Platinum
• Blue-black
• White
• Auburn
• Salt-and-pepper
• Ash brown

Warm hair colors include:

• Golden blond
• Brownish black
• Brown-gold
• "Dirty gray"

Once you have determined if you are "warm" or "cool," then you can find the eyeglass frame colors that will suit you the best.

Examples of frame colors best for warm coloring are:

• Camel
• Khaki
• Gold
• Copper
• Peach
• Orange
• Coral
• Off-white
• Fire-engine red
• Warm blue
• Blond tortoise

For cool coloring, the best eyeglass frame hues are:

• Black
• Silver
• Rose-brown
• Blue-gray
• Plum
• Magenta
• Pink
• Jade
• Blue
• Demi-amber tortoise
