These days the coolest shades for women and men alike are vintage aviator sunglasses. Nothing can out do that old school aviator look and the larger the better. Most trends don't last more than a couple of years but aviators still stand as king of all sunglasses. They've been around for decades and still to this date anyone can wear them and pull off a cool look. There are so many styles that anyone can wear them and still stand out from the norm.
Whether you are going for designer sunglasses or cheap sunglasses, aviators are always the best bet. I tend to lean towards the cheap side because I sometimes end up losing or breaking some, but I have to have more than one pair. The big mirrored aviators are excellent for being out and about in the sun. Not only do they look slick, but they are almost pitch black! You could probably look directly into the sun while rocking a pair(but I wouldn't recommend it!). The extra pair I always have are not quite so dark, so you can still have that vintage aviator look while you are inside at a mall or a party. With so many options from big to small, gold frames to plastic frames, you can find the best pair of aviators to go with every style you have and still break away from the crowd, even if everyone else has their own aviators.
So do yourself a huge favor, grab a pair of vintage aviator sunglasses. Look around, check out different styles and prices, you may even find a good deal and grab a pair for as low as five bucks. Stay cool people.
