Long gone are the days when sunglasses were primarily worn to protect the eyes from strong light or the intrusive gaze of strangers. They have become an essential fashion item that completes a chic look even without make-up. They are now such a popular accessory that everyone wears them on normal occasions, not just when they are on vacation. But how to choose the right ones?

◆ Oversized Like Jacqueline Kennedy Onassis

Former U.S. first lady Jacqueline Kennedy Onassis was a fashion icon and known for her various sophisticated looks, chiefly the oversized sunglasses that became her trademark. Now they have been in trend again for a while after Paris Hilton and Lindsay Lohan were pictured wearing them. One of the strengths of oversized sunglasses is that they look good on any shape of face.

◆ Aviators Like Brad Pitt

Aviators enjoyed great popularity at one time in Korea, where they were known as "Boeing" sunglasses. Now they are back, with Ray Ban and Gucci the frontrunners. They are versatile, and many Hollywood stars as well as Korean celebrities match them with both casual and formal looks.

◆ Funny Like Elton John

While some people favor a classical style, others strive to be different and create their own style. Elton John in his heyday had several hundred pairs of sunglasses and always stove for the most outrageous effects. This is a chance to be unique.

◆ Small and Round Like John Lennon

John Lennon shades are risky if your facial shape does not match them. But if you can pull it off, it can look sensational and earn you a lot of attention.
