Prince Harry and Meghan Markle have made a public appearance together in central London to attend a gala performance of the hit musical Hamilton.
Harry wore a Navy suit and tie but all eyes were on his wife who wore a very short, $475 black Judith and Charles tuxedo dress and black high-heel shoes. The daring outfit was cut well above her knees and showed off her legs.
The Duchess of Sussex also ignored royal protocol by not wearing pantyhose. The Queen requires all royal women to wear nude stockings while in public.
It is not the first time Meghan has broken the rules, though. She has previously stepped out without stocking, exposed her shoulders and also broke royal protocol by giving autographs and taking selfies.
The glamorous newlyweds arrived at Victoria Palace Theatre, escorted by a police motorcade, just after 6.30pm local time for the show and were greeted by hundreds of adoring fans.
The Duke and Duchess of Sussex were the guests of honour at the play and were to meet with the crew behind the production and its stars.
Money raised from the special performance will go towards Harry's longtime charity Sentebale, which supports the mental health and wellbeing of young Africans affected by HIV.
Prince Harry took to the stage after the show, earning big laughs from the audience when he momentarily broke into a song performed by the character of King George in the musical."
"That's enough - he did try, but I said no," he said, gesturing to the show's creator, Lin-Manuel Miranda, who stood behind him on stage. "I don't know how these guys do it, every single night, and in this heat as well," Harry continued.

Earlier, Kensington Palace released a statement explaining that "The evening will raise awareness and funds for Sentebale's work with children and young people affected by HIV in southern Africa."
"Over the course of the evening, Their Royal Highness's will meet representatives from Sentebale and Hamilton, including members of the cast and crew.
"At the conclusion of the show both The Duke of Sussex and Lin-Manuel Miranda, who wrote the show's book, music, and lyrics, will address the audience."
Hamilton, which has garnered strong reviews, tells the rags to riches story of one of America's founding fathers, Alexander Hamilton, who became the right-hand man of George Washington.
Prince Harry's ancestor, George III, features in the play and is portrayed in a comical light.
Harry and his friend Prince Seeiso of Lesotho founded Sentebale in 2006 and it has become one of Harry's premier causes.
In July, he made an appearance on behalf of the charity at the International AIDS Conference in Amsterdam where he joined Sir Elton John onstage to announce a billion-dollar endeavour to help reduce the spread of the virus.
Harry's mother Diana, Princess of Wales, was also well-known for her prominent role in destigmatising AIDS.
