Beautiful and comfortable Coach aviators!
Color: Shiny Light Gold, Lens Width: 57 Millimeters
Beautiful! I loved how they looked in the virtual try-on and they are even better in person. Aviator sunglasses are my favorite and these take it to the next level. They are classic and never go out of style. The size is perfect. The gradient brown is very nice and provides great sun protection and the frames are beautiful. The Coach logo is stunning. But even better is the comfort. The frame is just the right weight and they are comfortable for long periods. They came nicely packaged in a very nice Coach case. I am very pleased with this purchase.
