No Bright Polish Colors
There are even regulations about nail polish. Kate Middleton’s color choices are now very limited. She is only permitted to wear Nude 423 Allure (Essie) or Soft Pink 28 Rose Lounge (Bourjois). No bright colors are allowed. Actually, the Queen wore the same enamel shade since 1989. According to the royal protocol, the family must keep their nails natural tones for official events and absolutely no bright colors. Take the Queen for example, she’s worn that same enamel shade since 1989.
