Princess Eugenie has married her long-time partner Jack Brooksbank at a ceremony attended by the rich and famous.
A stream of celebrities, including Kate Moss, Liv Tyler, Demi Moore and Stephen Fry, entered St George's Chapel in Windsor ahead of the service on Friday.
Many of the 850 guests, including more than 40 royals, were holding on to their hats and dresses as strong winds blew through Windsor.
The ninth in the line to the throne waved at onlookers as she stepped out of the Queen's 1977 Rolls Royce Phantom VI at the West Steps.
Wearing a long-sleeved v-neck dress with a low back designed by Peter Pilotto and Christopher De Vos, she beamed as her proud father, the Duke of York, accompanied her.
The dress also included a number of symbols meaningful to the bride, including a thistle for Scotland, symbolising the couple's fondness for Balmoral, a Shamrock for Ireland as a nod to the Ferguson family, and the York Rose and ivy for the couple's home.
Buckingham Palace said the low back feature was specifically requested by Eugenie as a tribute to surgeons at the Royal National Orthopaedic Hospital, who corrected her scoliosis when she was 12.
The Queen lent Eugenie the Greville emergald Kokshnik Tiara, made in 1919, which she wore with diamond and emerald drop earrings which were a present from the groom.
Moments before her arrival, the groom entered the chapel where Meghan and Harry married in May, looking slightly nervous.
Princess Charlotte waved to the crowds as she arrived with a gaggle of young bridesmaids and pageboys, who included Prince George and Teddy Williams, daughter of pop star Robbie Williams and Ayda Field.
As Prince Andrew accompanied his youngest daughter up the aisle, Mr Brooksbank was visibly nervous but when she reached him, he grinned and said "you're perfect" and "oh, break my heart".
Classical singer Andrea Bocelli performed two songs during the ceremony, accompanied by the Royal Philharmonic Orchestra.
Eugenie's older sister and maid of honour, Beatrice, gave an animated reading from F Scott Fitzgerald's classic novel The Great Gatsby.
The Dean of Windsor David Connor, who officiated, said the passage was special for the couple as Eugenie read the book soon after meeting Mr Brooksbank on the ski slopes of Verbier in 2010 and immediately thought of his smile.
As the newest royal couple left the chapel they waved and treated the crowds to two quick kisses before they got into a carriage pulled by four grey horses.
After they paraded around Windsor in the carriage they were taken to Windsor Castle for a lunch hosted by the Queen.
This evening they will go to the Royal Lodge, the York family's official residence in Great Windsor Park, for a dinner hosted by the Duke of York.
