Article: That way your sunglasses will balance out your face when you’re wearing them. Wearing frames that match your face shape may accentuate the shape of your face, and they won't pop as much.  For example, if your face is more round, you could choose a pair of square, angular frames as a nice contrast. If you have a squarer face with a defined jaw, sunglasses with round frames may help soften the angles of your face. Keep in mind that frames on sunglasses are usually bigger than frames on eyeglasses. Choose frames that cover the width of your face. The top of your sunglasses should go up to your eyebrows and the bottom of your sunglasses should cover the raised, top portion of your cheeks.  Pro Tip: Good fitting frames won’t go past your forehead. Christina Santelli, professional stylist, tells us: "They can go higher if you want an oversized frame look, but for the most part, your forehead is a good stopping point." Metal and plastic are the most common materials used to make frames for sunglasses. Go with metal or plastic frames if you want something classic that will hold up well over time. Wooden frames are less common than plastic and metal frames, but they’re more expensive. If you don’t want the entire frame to be made out of wood, or wooden sunglasses are out of your budget, look for frames that have plastic earpieces with wood around the rims. Acetate frames won't irritate your skin when you wear them. They're also lightweight, and they're available in a wide range of colors.

What is a summary?
Choose a frame shape that contrasts with your face shape. Get frames that are proportional to your face. Choose a metal or plastic frame for something durable and cost-effective. Buy wooden frames if you want stylish, unique sunglasses. Get acetate frames if you want sunglasses that are hypoallergenic.
