5. Mixing Gold and Silver Jewelry

The old rule against mixing gold and silver jewelry no longer applies. Stylists now encourage layering gold and silver necklaces, stacking rings of different metals, and wearing mixed-metal watches for a modern, curated effect. This approach adds visual interest and avoids a matchy-matchy look that can feel dated. Celebrities like Hailey Bieber and Meghan Markle are often seen blending metals, proving that this “mistake” is actually a mark of confident, contemporary style.
