Princess Eugenie shares a first kiss at Royal wedding showing her scars in chic backless dress

On Friday, Princess Eugenie finally married her long-term partner Jack Brooksbank. Their marriage was held at St George's Chapel in Windsor.

The Princess shared her first kiss with her new husband wearing a white backless wedding dress. The dress showed her scars from a back operation when she was 12.

Princess Eugenie, 28, shared a kiss with new husband Jack Brooksbank, 32, on the steps of St George’s Chapel. Their wedding was one of the most celebrity-filled Royal weddings in history.

They invited 850 Royals, aristocrats, VIPs, and friends and their security cost taxpayers $2.6 million. Some of the celebrities in attendance were Naomi Campbell, Liv Tyler, Demi Moore, Robbie Williams, Ellie Goulding, James Blunt, Cara Delevingne, and Kate Moss.

The Queen and her husband Prince Philip, 97, also attended. Trying not to overshadow the couple, Prince Harry and his wife Duchess Meghan entered the chapel through a side door.

Prince William and his wife Duchess Kate also followed suit. Their children Prince George and Princess Charlotte were pageboy and bridesmaid.

Eugenie met Brooksbank in 2010 while skiing in Switzerland. BBC Royal correspondent Jonny Dymond said there were "lots of smiles and lots of nerves from the couple."

The bride’s dress was designed by Peter Pilotto and Christopher De Vos under the British label Peter Pilotto. The dress had a neckline that folded around the shoulders to a low back that draped into a full-length train.

The bride had specifically requested that the dress have a low back to show her scar from surgery to correct scoliosis when she was 12. On her head, she wore the Greville Emerald Kokoshnik Tiara, loaned to her by the Queen.

Eugenie's sister, Princess Beatrice, was maid of honor while Brooksbank chose his brother, Thomas, as his best man. The couple had a 20-page booklet which gave details of when the wedding party will arrive, the history of St George's Chapel, as well as information on the hymns, songs, prayers, readings and music.

After the wedding, the couple traveled from St George's Chapel along Windsor High Street and the Long Walk. They had an afternoon reception which was hosted by the Queen in St George's Hall at the castle.

An evening party will take place at the York family home, the Royal Lodge, in Windsor Great Park.
