Best Sunglasses Styles 2012

Why we love them: This time around white shades are a lot more chic than they were in the '80s. Rachel Bilson's Chanel frames are a perfect example of why they work and why we adore their fresh feel.

How to wear them: These shades pull double duty; depending on the frames they can go easily from more casual to more polished ensembles. Avoid really bulky frames if your face is on the smaller side, but opt for thicker styles if you have a rounder face shape.
