Louis Armstrong famously sang, "Life can be so sweet – on the sunny side of the street." That's even more true when you're wearing a stylish pair of sunglasses.

Aviator Style

In 1937, Ray-Ban created the first polarised sunglasses – for United States Air Force pilots. The large lenses (originally green) were made to give these eyes in the sky optimal protection and crystal-clear vision. Easily recognisable by their thin metallic frame with a double bridge and their teardrop shape, they were very trendy during the '50s – every man wanted to be imbued with their heroic vibes. Wanna channel your inner Tom Cruise in Top Gun? Get a pair of aviators and make them your own; it fits just about everyone and looks just as badass on the sidewalk as it does in the cockpit of a fighter jet.
