As the Princess of Wales attended an Easter service in Windsor at the weekend, it wasn’t her head-to-toe royal blue outfit that eagle-eyed royal watchers noticed.
It was the unexpected shock of red on the tips of her fingers.
The splash of bright polish is something seldom seen on royal mittens and, according to the Daily Mail, is thought to be because of the late Queen’s rules about nail polish.
Royal etiquette expert William Hanson told the Sun “hot red and bright pink, for example, are not correct, especially for official occasions and particularly during mourning”.
Instead, the Queen permitted barely-there shades such as “translucent or dusky pink” and deemed coloured nails “vulgar”.
