The Duke and Duchess of Cambridge were seated next to the Duke and Duchess of Sussex, who had to skip Eugenie and Jack's second wedding day due to their royal tour of Australia. Both Kate Middleton and Meghan Markle wore their own wedding dress designers to the nuptials: Kate in a pink Alexander McQueen dress and Meghan Markle in a navy blue Givenchy coat.
The foursome chatted and laughed as they awaited the bride's arrival, before sitting back and watching the door as the music started.
As Princess Eugenie walked in wearing her stunning Peter Piloto gown and the Queen's Greville Emerald tiara, Kate Middleton and Meghan Markle's faces were pure joy.
Kate and Meghan, who was married in the same location, Windsor Castle, on May 19th, both stared at the royal bride with huge smiles on their faces:
Of course, Prince George and Princess Charlotte were part of the bridal party, so Kate would have been also looking out for her eldest children to walk down the aisle.
The bride was accompanied by her father, Prince Andrew, Duke of York as she made her way up the stairs, showcasing the open back detailing on the gown.
Later, Princess Eugenie changed into a Zac Posen dress for the wedding reception.
