From the longer days to that one optimistic guy in shorts in flip-flops shivering through a rainstorm, finally there are signs that summer is coming. And as long as the sun shines, shades will never go out of fashion. They're the accessories that can make you feel like a movie star while popping out to buy some milk and they instantly conceal the signs of a late night while you're doing it.

But there's one small issue. Sunglasses are basically the fashion equivalent of umbrellas — because they go everywhere with you, they all too often go MIA. In fact, you've probably had quite a boring summer if you don't lose a pair to the surf, the coffee shop or a friend with sticky fingers.
