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 touching 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.

Actor Idris Elba tried his hand at DJing during the evening, the Daily Telegraph reported, and there was no first dance tune for the couple, rather the Whitney Houston track I Wanna Dance With Somebody was played, where everybody took to the dance floor.

But the fun did not stop when Frogmore House – the famous royal home loved by Queen Victoria – closed it 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,” adding “She was absolutely radiant.”

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 onto 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, with candyfloss on offer for those with a sweet tooth – 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.

Wedding guest Serena Williams uploaded a number of pictures of herself in her evening dinner dress to her Instagram account and joked about a little trick that ensures she has comfortable feet.

The tennis star, who became close friends with Meghan when the pair met at a celebrity football game back in 2014, wrote: “Little known fact: I often wear sneakers under my evening gown.”

In a touching symbol of their marriage a special information booklet for the evening event had the initials M&H at the top.

Professional polo player Nacho Figueras, an ambassador for Harry’s Sentebale charity, posted an image of the programme on a social media account.

While the 200 dinner guests were enjoying the Saturday celebration at Frogmore House some of the cast of Suits – the hit show Meghan starred in – staged their own event: a karaoke evening.

Rachel Renna, the make-up artist for Meghan’s fashion stylist Jessica Mulroney, posted a video on the internet of some of the actors crooning to songs.
