Princes William and Harry both wed their wives in lavish ceremonies watched by millions of people across the globe.
Both royal brides - the Duchess of Cambridge and the Duchess of Sussex - wowed in their stunning gowns and at each wedding, the brothers acted as each other's best man.
But despite some of the similarities of their big day, there was tradition that William chose not to follow - but Harry does.
And that is that Harry wears a wedding ring while William goes without.
It was revealed just before his marriage to Kate that William would not wear a ring.

Speaking at the time of his wedding, a Palace insider said: "He’s not one for jewellery. He’s never worn any. He decided he didn’t want to wear one now. It’s all down to personal preference."
Kate is said to back her husband's decision but she does wear a wedding band alongside her stunning sapphire engagement ring, which used to belong to her late mother-in-law Princess Diana.
Meanwhile, Harry can often be seen fiddling with his wedding ring at official engagements, which is a platinum band with a textured finish that is made by jewellers Cleave and Company.

Meghan Markle's wedding ring is also made by Cleave and Company and is fashioned from a piece of Welsh Gold - as is tradition for royal brides.
She wears it alongside her engagement ring, which consists of two diamonds from Princess Diana's collection and one from Botswana.
Shortly after their first wedding anniversary, the stunning piece was redesigned, and the plain gold band was replaced with a thinner micropavé one. It was unclear why she made the change or when it happened.

Meanwhile, a royal documentary earlier this year revealed that Prince Harry "selflessly" gave up his mum Princess Diana's iconic sapphire engagement ring so his brother Prince William could give it to his fiancee Kate Middleton.
After Diana died in a car crash in Paris in 1997, Prince Charles allowed his sons to select pieces from her jewellery collection to keep.
It's believed the sapphire ring went to Harry, while William chose a gold Cartier watch.
But in the programme, The Diana Story, the princess' former butler Paul Burrell explained that shortly before William proposed to his now-wife Kate in 2010, Harry offered his brother the chance to give his bride-to-be their mother's ring.
