To this day, Prince William and Princess Kate's royal wedding remains fresh in the minds of fans across the globe despite thirteen years passing since they said their vows.
One of the most memorable parts was the couple's much-anticipated outfits. As they exchanged vows in Westminster Abbey on 29 April 2011, the Princess of Wales (then Kate Middleton) looked resplendent in a lace corset gown by Sarah Burton for Alexander McQueen, while her royal groom wore his red Irish Guards uniform to reflect his most senior military position.

He rocked his high-neck black wool coat as he placed his hands on the waist of his wife, who was still wearing her first gown. The photo was taken during his afternoon wedding reception at Buckingham Palace, hosted by the late Queen.
Kate's second wedding dress
Meanwhile, Kate made her grand entrance in her second wedding dress – a strapless Alexander McQueen dress with an embellished waist and fluffy cardigan – while leaving Clarence House for the couple's evening reception. At the time, William had made yet another swap, stepping out in a black tux and bow tie.
Designer Sarah opened up about the process of creating the two wedding dresses during a chat to the New York Times, T Magazine.

I respect the intimate nature of that lovely project and I respect the friendships that were forged during it... an instinctive, intelligent, imaginative young woman's wish for a beautiful wedding dress - or any kind of dress - is the most natural thing in the world. I was honoured to pick up the challenge and always will be."
William 'frustrated' over wedding uniform
It is not clear why the Prince changed more times than his bride, but William had reportedly wanted to wear his black ensemble for his entire royal wedding day. His younger brother Prince Harry claimed in his book Spare that William was left feeling "frustrated" and "gloomy" after the late Queen Elizabeth II overruled his wedding outfit request.
The red jacket featured the Irish Guards’ distinctive arrangement of buttons and a gold trim, alongside gold sword slings, the Garter Sash with the Wings of the Royal Air Force, the Garter Star and the Golden Jubilee Medal.

"I was given a categorical: 'No, you’ll wear this!'" he said. "So you don't always get what you want, put it that way… But I knew perfectly well that it was for the best. That 'no' is a very good 'no'. So you just do as you’re told!"
Wedding guests' multiple outfits

Photos show Princess Kate's family also chose glam evening gowns. Mother-of-the-bride Carole was pictured in a tiered black evening gown with flutter sleeves and a V-neck, while bridesmaid Pippa rocked an emerald embellished second dress.
