There’s something about length that gives many an object—from long-stem roses to thigh-high boots—extra drama. In jewelry, long earrings (no matter the material) are the quickest way to add a dash of sexiness to just about any outfit. Whether they’re sterling drops to spice up a buttoned-up blouse or gemstone-studded numbers that balance a sequined neckline, the lean and lovely silhouette offers subtle, seductive glamour at any time of day.1.
