Face Shape

While pulling your hair back so it does not block your face, look in the mirror.  If your chin and jaw line is more angular, then you have a square-shaped face and you should look for rounder sunglasses.  If you have more of an oval or round face, square or angular sunglasses will work better for you.

	For example, Paris Hilton has a square jawline and face, therefore round sunglasses look better on her.
Nicole Richie, however has a more oblong or round face, so sunglasses with hard angles look good on her.

Face Size

Large and oversized sunglasses frames are all the rage these days, but remember, if you have large or prominent cheeks, large frames may rest uncomfortably on them and irritate the skin as you smile or talk.  After a while, you could experience red marks on your cheeks, and no fashion accessory looks good if you are uncomfortable wearing it.

Try to find a pair of sunglasses that are in good proportion with your face size.  A small pair of sunglasses on a large face will only accentuate the size of the face and a large pair will do the same to a small face.

Color

Like any other fashion accessory, the color of the sunglasses can accentuate color on your face or clothing.  All complexions fall into one of two basic color bases: cool or warm.  A cool complexion has a fair or pale color that commonly has rosy cheeks and sunburns easily.  Cool colors have blue or pink undertones.  Warm complexions have golden or olive tones which tan easily.

Some examples of frame colors best for warm coloring are: camel, khaki, gold, copper, peach, orange, coral, off-white, fire-engine red, warm blue and blond tortoise. For cool coloring, the best eyeglass frame hues are black, rose-brown, blue-gray, plum, magenta, pink, jade, blue and demi-amber (darker) tortoise.
