Prince Harry has thanked his wife’s wedding dress designer for transforming Meghan into an “absolutely stunning” bride as details of the all-night royal partying emerged.

The revelation came as reports revealed guests celebrated the couple tying the knot by downing themed cocktails, eating up-market fast food, watching a spectacular fireworks display and dancing to a celebrity DJ.

But the fun did not stop when Frogmore House – the famous royal home loved by Queen Victoria – closed its doors, as some guests are said to have staged an after party at top London hot spot Chiltern Firehouse.

Following the exploits of Saturday night, Harry and Meghan left Windsor Castle during Sunday afternoon after being hosted by the Queen and Duke of Edinburgh over their wedding weekend.

British designer Clare Waight Keller, who was spotted arranging the Duchess of Sussex’s veil and train just before she processed into St George’s Chapel, said soon after the ceremony Harry rushed up to praise her efforts.

She said: “He came straight up to me and he said ‘oh my God, thank you, she looks absolutely stunning’.”

Asked about the moment Meghan was able to look at herself dressed and ready in the mirror on Saturday morning, Ms Waight Keller said: “She was just glowing.”

Meghan’s hair stylist Serge Normant said it was “dreamy” to work with Meghan, creating a bun that was “messy, in a controlled way”.

Just hours before she emerged on to the steps of St George’s Chapel to worldwide audience, Meghan appeared relaxed, Mr Normant said.

“She was calm, yeah. Chatty, absolutely. We were definitely having exchanges, yeah for sure,” he said.

“She was very happy. It was a beautiful morning, just the perfect morning to get married.”

The Prince of Wales staged the black-tie evening dinner for his son Harry and new daughter-in-law Meghan, who arrived in a environmentally-friendly 1968 Jaguar E-Type Concept Zero that ran on electric power. Guests dined on posh burgers among other dishes and there was reportedly a cocktail on offer named When Harry Met Meghan, a reference to the romantic comedy When Harry Met Sally, starring Meg Ryan and Billy Crystal.

And just hours after fireworks lit up the night sky over Windsor Castle in a spectacular finale, the Duchess of Sussex unveiled her aspirations for her new role as she received her own web page on the official royal.uk website yesterday.

The 36-year-old’s online biography champions her history of charitable work and “lifelong commitment” to social justice and women’s empowerment. It also features her quote from a United Nations conference in New York in 2015, when she said: “I am proud to be a woman and a feminist.”

The web page states: “As well as undertaking royal duties in support of the Queen, both in the UK and overseas, the Duchess devotes her time to supporting a number of charities and organisations. “

The couple’s honeymoon destination has not been officially revealed, although there are suggestions it may be in Namibia, south-west Africa.
