When we think of signature style, the always chic, always cute Rachel Bilson tops our list. From running errands around town to hitting the red carpet, Bilson has never missed a fashion note. Her key piece? It's those cool blazers — Bilson has a special penchant toward the Vanessa Bruno variety — she keeps pairing with just about any ensemble. We can see why; blazers instantly inject a polished touch to Rachel's more casual daytime looks, and at the same time, we love how she tempers the menswear-inspired trend with girly dresses on the red carpet.
