1. Consistency. That means the frame color is consistent with the color of your outfit. For example, if your dress is red, then choose a frame with a tone of red. If your shirt is white, a white frame will look good on you. This is the safest choice and you could never go wrong. A pair of black or brown frame oversized sunglasses is, however, an essential item in summer and will go with any color of outfits. The fashion icon Victoria Beckham brought this fashion trend and now almost every girl has a pair of those. Get the celebrity's look if you haven't got one as summer is coming soon!

2. Contrast. That means choosing a frame that has a strong contrast with the color of your outfit. For instance, if you like wearing the outfits with cool tones (purple), then you can select the frames with warm tones (yellow). If most of your outfits are warm-toned (red), a blue frame will make you stand out in the crowd.

3. Embellishment. A sharp-colored frame with a one-colored dress will make a fabulous combination. A bright-colored frame can turn a boring look glamorous. It is a must-have item in this summer.

But the thing we need to be careful about is because of the temper brought by the weather in summer, if you don't choose the frame with the right color, it can be seemed unnecessary. Therefore, you should wear the frames that can catch the eyes but aren't too sharp. Pink or gray stripy T-shirt, as an example, can match up with the red frame sunglasses in order to show the elegance along with the youthfulness.

In winter, you can also wear a pair of red frame glasses to match up with a red-toned scarf to show your trendy taste. A lot of celebrities including Lindsay Lohan, Gwen Stefani, Paris Hilton and Sienna Miller have chosen red frame sunglasses to style themselves. If you are tired of all your boring sunglasses, get a pair of red frame sunglasses now! They are perfect for summer and have definitely become a hot trend this year!
