Before making a stylish appearance at Sunglass Hut in Santa Monica to launch the Spring 2012 collection yesterday, Rachel Bilson chatted all things sunglasses with us. And although she told us her ultimate favorites are Ray-Ban Wayfarers, the actress-slash-style-guru opted to wear fresh white Chanel shades to the event. Keeping with the red-pant trend, Rachel wore a wide-leg Isabel Marant pair with ShoeMint Chloe platforms and an Elizabeth and James fox necklace. Her simple white tee and oversized black blazer allowed the pants to take center stage. What's great about Rachel's creation is that it will work everywhere from the office to a restaurant to a lounge, so if you love it as much as we do, shop the pieces below.
