There's one common denominator unifying all of Kate Bosworth's street style — and it's not just the fact that it's all crafted flawlessly. Topping off every perfect snap is a pair of killer shades — the kind so insanely cool, we had to know just where to find them. Turns out, Kate's selected Céline's awesome wayfarers ($239, originally $360), to lend the finishing cool-girl touch on just about anything. The proof is in this batch of artfully assembled looks — from a dressed-down day in Sundance (and even with a few flurries!) to a sunny LA stroll, these shades are a testament to the power of great accessories. In the market for your own pair? Get shopping before they sell out, or your best bet may just be eBay.
