Ms Markle wore Essie shade Ballet Slippers for her big day, the brand has confirmed, which happens to be the only nail polish the Queen has worn since 1989.
The royally approved polish is also a favourite of Emma Stone, Mandy Moore, Karlie Kloss and Meryl Streep, who wore it to play formidable fashion magazine editor Miranda Priestly in The Devil Wears Prada.
Royal protocol stipulates that only natural-looking nail colours can be worn in public, with bright shades strictly forbidden.
Kate Middleton has always taken this particular rule very seriously: she’s only been photographed with a manicure once, on her wedding day, when she wore another Essie pale pink, Allure.
