Pick the Best Glasses for Your Face
The first step to doing this is to figure out the shape of your face. Your choices are round, oval, square or heart. In order to determine which of these is yours (if you can't simply tell by looking), you can stand in front of a mirror and trace the outline of your face on it with something that will wash off, like eye pencil. Stand away from the outline and try to determine what general shape category it falls into. For most people, the shape of their face is pretty obvious, so don't overthink it. Oval faces are supposedly the best because almost anything looks good on you - hair styles, glasses, you name it. Good for you.
So, now that you know what shape your face is, you don't want to pick the same shape of eyeglasses. If your face is round and you wear a round pair, it's only going to accentuate the fact that your face is round and make you look unduly chubby. If you pick a square shape, however, it will elongate your face, giving you an illusion of a thinner face. If you have a square face, you might consider doing something oval or round. This is another area where you need to pick what's going to look best on you, and let your inner personality come out. After all, you're going to have to wear them all the time, and it's going to be the first thing people see when they look at you. Pick glasses you absolutely love, and that reflect who you are.
Sunglasses are the same way, but you can take more risks with these. Go for a bolder pair, if you want, because you don't have to wear them all the time. Big sunglasses are in, but you don't have to get absolutely huge ones - slightly larger than normal still makes a statement without making you look like Carrie Donovan. You can do almost anything with sunglasses - aviator, rhinestoned, colored lenses - anything goes with these. Have a little fun with them! But make sure you get a pair that is still going to protect your eyes from the harmful rays of the sun. Losing your eyesight is not attractive, nor popular.
