Princess Eugenie wedding in pictures: Splendid hats and gusts of wind

The wedding of Princess Eugenie, the Queen's granddaughter, and Jack Brooksbank took place at St George's Chapel in Windsor Castle.

We take a look at some of the most striking pictures from the day.

The ceremony was attended by 850 guests, with 1,200 members of the public selected by ballot listening to a live broadcast in the castle grounds.

Princess Eugenie was led down the aisle by father Prince Andrew, Duke of York, seen below climbing the steps of the chapel.

Bridesmaids and page boys helped Princess Eugenie on her big day, including Princess Charlotte of Cambridge, seen below on the left.

Theodora Williams, daughter of Robbie Williams and Ayda Field, was also a bridesmaid, seen below.

Windy conditions outside meant that the bridesmaids and pageboys were unsteady on their feet.

Met Office forecaster Helen Chivers said that wind in the Windsor area was forecast to be 30-35mph.

Princess Eugenie passed her bouquet to a bridesmaid before she got married.

The Queen and the Duke of Edinburgh were at the chapel for the wedding, seen here with Prince Charles, Prince William, Prince Harry and Catherine, Duchess of Cambridge.

The princess's sister and mother, Princess Beatrice of York and Sarah Ferguson, were at the ceremony, dressed in vibrant blue and green.

Celebrity guests included Naomi Campbell sporting a chic black fascinator, seen below.

Demi Moore arrived dressed in burgundy.

Ellie Goulding (left) was seen in a pale blue and silver dress.

Actress and model Cara Delevingne wore an unusual outfit, opting for a top hat instead of a traditional fascinator, along with a black suit and tie.

The Royal Family sat together as they watched the wedding ceremony.

Princess Eugenie's wedding dress was designed by Peter Pilotto and Christopher De Vos of British-based label Peter Pilotto.

Notably, the princess chose not to have a veil, showing off the low back of the dress.

The Queen's granddaughter had major surgery on her back to treat a curvature of the spine at the age of 12.

The princess said she hoped showing her scar would honour those who had helped her and inspire others with the condition of scoliosis.

After the wedding, the married royal couple climbed into their carriage.

Crowds cheered the pair as their carriage wound its way through Windsor High Street and the Long Walk, before an afternoon reception hosted by the Queen in St George's Hall at the castle.

The happy couple left the reception a silver DB10 Aston Martin, originally made for the James Bond movie Spectre.
