Lady Amelia Spencer parties in second wedding mini dress with husband Greg Mallett

Lady Amelia Spencer – the cousin of Prince William and Prince Harry – looked stunning in two wedding dresses when she married Greg Mallett on 21 March.

After walking down the aisle at Quoin Rock Manor House in South Africa’s Western Cape in a custom Versace gown, Princess Diana's niece swapped the floor-length ensemble for an equally beautiful mini dress.

Photos shared exclusively with HELLO! magazine show the newlyweds holding drinks and sharing a kiss on the dance floor surrounded by their friends and family. Featuring several notable similarities to her first bridal gown, Amelia's second dress from Pronovias boasted a sweetheart neckline, puff shoulders, long sleeves, an embellished bodice and a skirt that fell to her mid-thigh.

Amelia later showed off the backless design as she hugged her new groom, who had swapped his blazer, crisp white shirt and black bow tie for a more relaxed black open shirt.

The model kept some items of her bridal look the same throughout the day - she wore her hair in a sleek bun finished with an embellished hair accessory, alongside Jimmy Choo heels and her sparkly diamond engagement ring designed by Greg. For the ceremony, she paired them with her Versace dress, which she told HELLO! was "the most beautiful dress I’ve ever seen."

Crafted over two and a half months, the gown featured a two-and-a-half metre train, Swarovski crystals, a hand-embroidered neckline and structured shoulders, with intricate flower patterns running throughout. Amelia added an elegant five-metre-long veil made out of fine silk tulle.

Amelia explained her dress had a special link to her late aunt Diana, who was a close friend of Gianni Versace and a wearer of his designs.

"I think she would be very proud to see me on my wedding day. I know the Versace family also absolutely love Diana, so there’s a very special connection that we have," explained Amelia, who was only five years old when Diana passed away in 1997.

Recalling the emotional moment she saw her dress in person for the first time, during one of her fittings, for which she was joined by twin sister Lady Eliza and older sister Lady Kitty, Amelia said: "My eyes filled up [with tears], so did my sisters’. When I put it on, I was just so happy and grateful that it was my dream dress, I didn't change one thing. It fit like a glove."
