Best Bet: Octagonal Earrings

It's hard to top the easy versatility of classic black and white. Inspired by the Australian wallpaper designer Florence Broadhurst (of whom Marc Jacobs and Stella McCartney are fans) these earrings pair octogonal resin baubles with fourteen-karat-gold beads. Their shape gives them an Art Deco feel, while the small gold spacers provide a light-catching contrast.

Octogonal earrings, $78 at Kate Spade or online.
