Nail Polish Colors The Royals Are Forbidden From Wearing

Even though Ballet Slippers — which due to the Queen's blessing, a bottle sells every two seconds — is a very soft pink, nearing on a shade of nude, it is still an exception to the Queen's own rule by being a color (via Cheat Sheet). It's actually been a staple nail polish for the Queen since 1989, when her hairdresser requested the now-iconic shade on behalf of her Majesty. This isn't exactly the only exception to the rule either.

Though the royal women have extensive beauty guidelines they adhere to, there is a loophole that many mere civilians overlook. Apparently, the natural-looking nail polishes and other royal protocols must only be followed for state occasions. But, even at other events, most royals shy away from bright hues, and especially fake nails, since the Queen dislikes them (via Southern Living).

Besides, the former Duchess of Sussex wasn't the first to break protocol and choose a dark, trendy shade for her manicure. Marlene Koenig, a historian and writer for the blog, Royal Musings, explained, "Diana wore it, Catherine's worn it. Royals around the world have worn it."
