When we spotted Mary-Kate and Ashley Olsen sitting pretty on J.Mendel's NYFW front row today it wasn't their crisp monochrome outfits or eclectic cool collection of gold finger bling that got our attention (although it does make a pretty styling side-note). The Olsen's coordinated their eyewear before leaving the house — both donning classic aviator shades to shield their eyes from those blinding runway lights, and in the process reminded us just how cool this iconic sunglass style is. Don't own a pair? Well, it's time to invest! Taking MK and Ashley's lead, we've sourced ten of the best aviator sunglasses for your perusal.
