At this point, we know a lot about Queen Elizabeth II. We know what she eats in a day, that she won't travel without cake, that she loves a good bold-colored coat (and hat) and that she uses her handbags to send secret signals to her staff.
Now, this just in: she seemingly only wears one nail polish color, and it's essie's Ballet Slippers. And it's only $9.

According to essie's website, in 1989, "Queen Elizabeth's hairdresser [sent] essie a letter requesting ballet slippers - the only color Her Majesty would wear." Ballet Slippers is a perfectly pale and understated pink, so we understand why the queen would opt for it (especially given the vibrance of her attire).

She's not the only fan, either. As Insider points out, Miranda Priestly of "The Devil Wears Prada" approves, too.
