As per Allure, there are a few guidelines to remember when buying sunglasses for an oval face. First one? It's all about size. As Bobbi Brown told the outlet, "if you have smaller features, avoid thick, large frames, as they'll overwhelm your face." Since oval face shapes are known for their delicate silhouette and their "gentle narrowing at the forehead and jaw," anything too big will drown out your gorgeous shape. Since "your main concern should be the size and the proportion to your features," most sunglasses will work, just make sure to avoid frames that are wider than your face.
To really play up your balanced face shape while adding some edge, try soft angular frames (via Oprah.com). Le Specs Air Heart Sunglasses have a rounded-yet-geometric edge in a large cat-eye shape that will look amazing on you. As per Eye Buy Direct, rectangular frames are "perfect for oval faces," enhancing your natural symmetry while adding some angles and definition to your soft silhouette. Try Ray Ban's Original Wayfarer Classic in tortoiseshell for a flattering, vintage touch. Traditional aviators also look great, particularly ones that hit right at the edge of your face and play with geometrics like glitzy Illesteva's Patmos Sunglasses.
Other hits for oval faces? Square shapes will create the illusion of sharper cheekbones, while bright colors will add even more interest to your look. Try Ray Ban's Square 1971 Mirror Evolve in sunset pink, which should fit into any fun summer plan.
