Lady Eliza Spencer was a vision in white on 20 December as the model, and her fiancé, Channing Millerd, brought together a group of their closest friends and family to attend a party celebrating their engagement.
The niece of the late Princess Diana, 33, looked radiant in a crisp white mini dress covered in dainty appliqué flowers. The piece featured a beautiful square neckline, fitted bodice, and A-line skirt.
She teamed the dress with white heels and drop earrings and styled her platinum blonde hair in loose waves, which were gathered into a half-updo. Meanwhile, her entrepreneur beau wore a blue linen shirt and white trousers, both perfectly suited to the rooftop beachside spot in Cape Town.
Also in attendance was Eliza's mother, model Victoria Aitken, as well as her two sisters, Lady Kitty Spencer, 34, and Lady Amelia, 33, and half-brother, Samuel Aitken. All the ladies got the bride-to-be's stylish memo, rocking gorgeous sundresses and peep-toe heels.
Lady Eliza and Channing's love story
Lady Eliza and Channing go way back, having met at a dinner party in South Africa (where the Spencer girls were raised) 15 years ago, which had been arranged by her twin sister Amelia's husband, Greg Mallett, who was a longtime friend of Channing's from school.
"I'd been single for about two years and wasn't really socialising much. I didn't plan to go, but Amelia and my best friend dragged me there," Eliza told HELLO! in her exclusive engagement interview earlier this month. "That's where I met Channing for the first time."
Channing pops the question
After nine years together, the pair got engaged in private in Santorini in July, with Channing popping the question with a beautiful 2.5-carat, pear-cut diamond set ring.
"I went shopping with my dad and brother-in-law, visiting many different diamond merchants in South Africa, trying to find the perfect stone. I eventually found it in a bespoke jewellers in Cape Town, then designed the ring myself," the groom-to-be told us. "I had a very clear vision – although perhaps there was some subliminal messaging imparted throughout the years."
"I told him the shape that I loved," Eliza told us. "It's perfect – the most beautiful ring ever – and so special that it's from South Africa."
Though the couple hasn't yet set a location for their big day, they did hint at possible options. "Some of our best memories have been made in the Mediterranean. Then, at the same time, all of our friends and family have done weddings in Cape Town," Eliza said.
"I've never been to Lake Como, but it looks so beautiful," she continues. "I think that would be my dream destination, but we still have to visit it first."
HELLO! will be revealing more details about the secret engagement party in the new year.
