Prince Harry and Meghan make their first official appearance as a married couple

Prince Harry and Meghan Markle's wedding really was the wedding of the year. The nuptials, which took place at Windsor Castle on Saturday 19th May, were even lovelier than everyone was expecting, and everything went off without a hitch - mostly.

Of course, Meghan looked absolutely stunning in her beautiful Givenchy wedding dress designed by British designer Clare Waight Keller, and had national flowers from all 53 of the Commonwealth countries sewn into the veil.

And the royal couple have now made their very first public appearance as husband and wife with their new titles of the Duke and Duchess of Sussex, a title that had been extinct since 1843 but has been resurrected for Harry and Meghan.

Appearing at Prince Harry's father Prince Charles' 70th birthday patronage celebrations at Buckingham Palace in London, the couple looked just as happy and in love as they did on Saturday.

Meghan wore a stunning cream-coloured pencil dress with a co-ordinating hat and shoes, whilst Harry opted to match his new wife with a waistcoat of the same colour along with a bright blue tie.

Meghan was also pictured laughing along with her new parents-in-law, Prince Charles and Camilla, at the celebrations.

Meghan's relationship with Prince Charles has touched many fans of the Royal Family, especially after she asked him to walk her down the aisle at the wedding as her father was ill and unable to attend.
