No doubt few can believe this event happened just over a year ago.
The handsome couple posted some never-seen-before photos from the wedding to mark a year from the day.
Body language expert Judi James told Express.co.uk what she believes the couple aimed to communicate with their fans.
She compared these new images with what we saw on their wedding day.
She said: “What we saw on the day was Meghan’s strength of spirit and confidence shone on the day as she walked proudly up the aisle by herself with not one non-verbal sign of anxiety or nerves.
“Her smile appeared to be used to reassure the far more jittery and almost tearful Harry.”
However, this image shows a different side to the proceedings, with Meghan looking “shy”.
Judi went on: “What they’re showing us here is Harry standing tall and more protective here, with Meghan lowering her head and her eyes in a gesture that can appear shy and quite submissive.
“But it’s also the shared humour that stands out here.
“Harry’s grin seems to be partly an expression of adoration and partly about him adopting his signature fun role in the royal family, making Meghan laugh and sharing the moment of humour with her.”
Harry and Meghan’s heartfelt post was captioned: “Happy one year anniversary to Their Royal Highnesses, The Duke and Duchess of Sussex!
“Today marks the one year anniversary of the wedding of The Duke and Duchess of Sussex.
“Their Royal Highnesses exchanged vows at St George’s Chapel within the grounds of Windsor Castle on May 19th, 2018.”
It went on: “A message from The Duke & Duchess: Thank you for all of the love and support from so many of you around the world. Each of you made this day even more meaningful.”
One image chosen by the couple showed Prince Harry and William on the morning of his wedding day.
The two brothers look up through a stairwell at a camera, seemingly leaving for the church.
Harry smiles up at the camera while his older brother William walks behind him, also looking towards the lens.
Judi James, a body language expert, said the picture was an “intriguing choice”.
She told Express.co.uk: “In the face of rumours of rifts between the two brothers this looks like an intriguing choice of pose to have selected.”
Rifts between Prince Harry and William and their wives have made a number of news reports in recent months.
Another body language expert told Express.co.uk that Prince Harry and William “do not look very happy” together at recent events.
Who is Meghan Markle? Quick profile
Meghan Markle was born Rachel Meghan Markle, on August 4, 1981 to parents Doria Ragland and father Thomas Markle.
Her father was previously married to Roslyn Loveless and Meghan has two elder half sibling – sister Samantha Markle and brother Thomas Markle Junior.
Meghan’s first television appearance in the USA was in an episode of the medical drama General Hospital in 2002.
She later moved on to roles in CSI, Without a Trace and Castle along with bit parts in Hollywood films including Get Him to the Greek, Remember Me and Horrible Bosses.
Meghan was also a “briefcase girl” on Deal or No Deal – but her most famous role was as Rachel Zane in legal drama Suits, which launched in 2011.
She was written out in the finale of the seventh series when her character got married, which aired in April 2018 – just before she got married herself.
Charity and humanitarian work
Meghan Markle’s career in television has gone hand-in-hand with her support for causes close to her heart.
She wrote about the stigma around menstrual health in an article for Time magazine and was a Global Ambassador for World Vision Canada – with whom she travelled to Rwanda for the charity’s Clean Water Campaign.
And her commitment to gender equality has seen her work with the United Nations – receiving a standing ovation in 2015 for her speech to mark International Women’s Day.
In September 2011, she wed film producer Trevor Engelson, who she began dating in 2004.
But the pair divorced two years later in August 2013, citing irreconcilable difference.
She was in a relationship with celebrity chef Cory Vitiello for almost two years, before they broke it off in 2016 but the two remain good friends.
And in June 2016, she met Prince Harry on a blind date set up by a mutual friend.
Their relationship began in October that year and just over one year later, on November 27, 2017, the pair announced their engagement.
They married on May 19, 2018 at St George’s Chapel in Windsor Castle.
Some have claimed Meghan Markle is the first mixed-race member of the Royal Family.
Historians are still arguing about Queen Charlotte, the wife of King George III.
But Meghan will be the first royal to openly embrace a mixed-race heritage.
She has written about the difficulties of being a biracial actress in Hollywood as she claims she is not black enough for some roles and not white enough for others.
