It’s time to consider this season’s most stylish eyewear offerings for sunny days and which variety will work best for your face shape and hair color.

Color

While classics such as black and tortoiseshell will always be in style, one of the main ways designers updated retro shapes for this season was with a surge of color.

While Roberto Cavalli has infused patterns from its runway collections into designs, pink is one of this season’s most dominant colors for frames, ranging from pastels at Dolce & Gabbana and Prada to hot pink at Miu Miu.

Going even bolder, Stella McCartney favors red, while yellow frames were all over the catwalk at the Marni Spring/Summer 2012 show.

Meanwhile, colors in Zac Posen’s debut sunglasses line with international eyewear brand Illesteva include yellow, green and leopard print.

When it comes to choosing which color to select, cool-colored frames look best with blonde hair, while dark shades complement brunettes.

Shape

Shape-wise, retro-influenced styles dominate the Spring/Summer 2012 sunglasses trends. The cat’s eye shape is refusing to go away, having made an impact at Spring/Summer 2012 ready-to-wear shows including Moschino and Rochas, where colorful 1950s-style shades were given a splash of color.

Dior, Miu Miu and YSL are just some of the other labels embracing the feline shape for this season, as is Nicole Farhi. This style flatters most face shapes, and works particularly well on oblong-shaped faces by breaking up the lengthiness.

Another vintage favorite noting a resurgence this season is the circular frame. The perfectly spherical style has been embraced by designer labels ranging from Louis Vuitton to The Row for Spring/Summer 2012, not to mention celebrities including Beyoncé Knowles and Lady Gaga.

As well as being on trend, this style is extremely flattering for ladies with a squared jaw line, as it softens angles in the face.

Ladies with round shaped faces should adopt a more angular style though, to help break up the roundness of the features.

Marc by Marc Jacobs and Kurt Geiger are just two of the labels to have embraced the ever popular “geek chic” square shape for this season. Meanwhile, one style that comes back season after season — the aviator– flatters the top heaviness of a heart-shaped face.

Different takes on this trend can be found to suit all budgets from designer brands including Armani to the iconic Ray-Ban and high street varieties from Accessorize.
