Though it’s an unofficial rule, it is widely known that Queen Elizabeth found colorful nail polish distracting. Bright hues are not banned for the royals, but nude colors are a more practical choice for official engagements. Although Princess Kate has occasionally glammed up her toes with a bright pedicure, her bold manicure moment marked a fashion first in public. A few months after she married into the royal family, Meghan Markle shook up the unspoken style guide and wore black nail polish for a surprise appearance at the British Fashion Awards in December 2018. The Duchess of Sussex, 41, was pregnant with Prince Archie, now 3, and came out on stage to present her wedding dress designer Clare Waight Keller with the British Womenswear Designer of the Year award. Meghan’s black nails matched her one-shoulder gown of the same shade.
