Guests begin to arrive at the hotly-anticipated “society wedding of the year”.

Bold pops of colour appear to be the unwritten dress code.

Here comes actress Donna Air.

She’s greeted warmly by boyfriend James Middleton, brother of the bride.

One of the greatest tennis players of all time, Roger Federer, arrives hand-in-hand with his wife Mirka.

It’s Made In Chelsea star Spencer Matthews, brother of the groom and best man.

Hi there Princess Eugenie, with boyfriend Jack Brooksbank as her beau.

James accompanies mother of the bride Carole Middleton to the church.

The Duke of Cambridge, Prince William, and his brother Prince Harry, approach with minutes to go.

They’re looking in good spirits for William’s sister-in-law’s big day.

No sign of Harry’s girlfriend Meghan Markle, whom he later collected via a 100-mile trip to London, in order for her to join the evening celebrations. 

The Duchess of Cambridge, Kate Middleton, arrives on cue with little Prince George and Princess Charlotte.

Kate is wearing a  blush pink custom Alexander McQueen dress designed by Sarah Burton – the same woman behind her show-stopping wedding dress in 2011.

The Duchess seems to have no problem marshalling the group of infant bridesmaids and page boys.

They’re getting set for the arrival of the bride...

And here she is. Pippa Middleton arrives with her father Michael in the back of a vintage 1951 model Jaguar.

The bride works a romantic yet subtly fashion-forward gown by Giles Deacon, with a cathedral-length tulle veil by milliner Stephen Jones.

"I was thrilled to work with Pippa on her wedding dress," Deacon said. "The bespoke silk cotton lace was hand appliqued to create an illusion of the dress having 'no seams'. The lace bodice is embroidered with pearl detailing over an organza and tulle underskirt, which has layer upon layer to enable a floor sweeping movement."

A true big sister, Kate helps Pippa arrange her veil – just as Pippa did for her back in 2011.

The hour-long ceremony over, Princess Charlotte gets set with a basket of petals.

Spencer makes his way out of the church.

Proud parents of the bride, Carole and Michael.

And it’s the new Mr. and Mrs. – looking delighted to have sealed the deal.

They beam in front of crowds of press and onlookers.

Prince George leads the younger contingent of bridesmaids and page boys.

The happy couple share a kiss.

They’re clearly elated.

The wedding was a relatively intimate affair (compared to Kate and William’s extravaganza, at least), with 150 guests.

The bride and groom depart in a rare Jaguar E-type sports car.

The newlyweds wave to the crowds.

They’re off to join their guests at a reception and later a party at Pippa Middleton’s family home, where their loved ones were entertained in a £100,000 marquee, with ping-pong tables, a lavish banquet and a flypast by a Second World War Spitfire.
