Lauren tells me she won't invest in jewelry unless it's timeless, well-made, and versatile. This necklace decidedly ticks off all three requirements, especially when it comes to versatility—you can hardly tell it's even the same piece after she removes the longer chain. "The fabric of this blazer top doesn't work with a major jewelry moment, so I styled the necklace as a delicate choker this time. It is subtle yet still very prominent," Lauren says of how she chose to wear the Roberto Coin necklace.
