A cat eye sunglass frame is the shape that has earned its place because it actually works on most people. The upturn at the outer edge creates a gentle lift without requiring the perfect bone structure. These frames feel polished without feeling costume. The defined frame shape means they work with both casual styling and more formal occasions. A proper cat eye should feel balanced in proportion rather than exaggerated. The frame colour should complement rather than compete with your colouring. These are the cat eye sunglasses that prove a classic shape endures because it solves a real styling problem and looks good doing it. The shape creates structure without aggression.
