In case you're wondering, they're Mykita & Bernhard Willhelm's Franz Limited-Edition Aviator Sheet-Metal Sunglasses ($525), and they're currently on pre-sale at Patricia Field. The style was named for Franz Klammer, an Olympic gold medal downhill skiier who was known for his reflective eyewear on the slopes. The price is steep, yes, but it's worth it to channel Carrie B.
Sex and the City 2 hasn't even come out yet and I'm already going gaga over Carrie's wardrobe. I loved her Egyptian-inspired necklace, but her gold aviators are also pretty sick.
