Sunglasses are the ultimate outfit maker. They instantly add a cool factor to any outfit and also add the perfect finishing touch too. But eyewear trends are constantly changing and the big question is how do you keep up. Well for starters you don’t have to keep up. If you’re the kind of person that likes classics then you buy a pair of signature shades you love and stick with them. But if you like changing things up then the key is to not spend too much experimenting with trends.
