Style isn't always functional, but when it comes to your eyes, it's best to choose a sun spec that protects your eyes while keeping your look effortlessly fabulous. Sunglasses are wonderful accessories to add to an ensemble, and the right pair can make or break a look. There are so many sizes and styles for shades but there are a few key rules to follow. Staying on trend with sunglasses is fun if you can find an inexpensive pair of white-rimmed or oversized specs at the local flea market, but if are looking to invest in a sturdy and powerful pair that say you are ready for anything and flatter your face, some retail research needs to go into your purchase. The frame you choose for sunglasses should be in proportion to your face. A smaller frame looks best on a smaller face so don't go for the oversized shades. Stick with something that's a bit more narrow in width. Keep the larger frames for a larger face. As a general sunglass style rule of thumb, the frame shape should be the opposite of the shape of your face. As for maintenance, make sure to take good care of your sunglasses by washing them in non-abrasive soap and warm-water. Dry them with a lens-cloth or cotton towel. Never use paper towels. And always store them in their case to avoid scratching and debris build-up.
