Princess Diana‘s twin nieces Lady Amelia and Lady Eliza went for a decidedly elegant look in ankle-length dresses for the launch of Swaine’s new flagship store.

Located just down the road from the iconic Fortnum and Mason department store, the retailer is one of the oldest names in luxury goods in London, beginning in 1750. 

Heading out to support the brand, Lady Amelia and Lady Eliza opted for chic summer dresses. 

Clutching a pale blue handbag, Eliza, 30, looked incredible in a forest green lace dress, with a Peter Pan collar, and a sweet string tie at the neck. 

The intricate design also featured diamanté buttons down the front and a bandeau underdress and tiny butterfly sleeves.

Bringing the look together was a thick green ribbon belt, that showed off the socialite’s slender waist. She finished her elegant look with silver chain strappy sandals and an immaculate pale pink pedicure. 

Keeping the focus on her dress, Eliza wore her long blonde hair up in a chic knot and decided to enhance her natural beauty with minimal make-up and just a sweep of bronzer. 

Lady Amelia also opted for a long dress for the summer evening, opting to wear a pale pink dress with beautiful covered buttons down the front. 

The elegant number featured a high neck with a twist element, decorated in delicate yellow flowers with black stems. Amelia accentuated her flawless white nails by carrying a mini black box bag and strappy high heels.

Amelia and Eliza, who moved from Cape Town to London in 2021, are the daughters of Princess Diana’s brother Charles Spencer and his first wife Victoria Aitken.

Lady Eliza and Lady Amelia grew up between Constantia, South Africa, and their family’s seat, Althorp. 

Since moving to London full time in 2021, Lady Eliza and Lady Amelia finally began stepping out of their eldest sibling Lady Kitty Spencer’s shadow.

The twins, who are both signed to Storm Model Management, quickly started appearing in society magazines like Tatler and Hello.

Amelia and Eliza previously said they are looking forward to fulfilling long-held ambitions; Amelia hopes to become a wedding planner and Eliza dreams of being an interior designer.  

This summer the twins have already attended a number of high profile fashion and society events – notably the Chelsea Flower Show.

It comes shortly after Amelia’s South African wedding in March. 

Amelia and her husband Greg Mallett first met through mutual friends in Cape Town 13 years ago. In July 2020, Lady Amelia got engaged to long-term boyfriend Greg following a romantic proposal in South Africa.

The society beauty, who is the cousin of Princes William and Harry, met her real estate beau while they were both studying at the University of Cape Town.

The couple were together for 11 years before Greg, 32, popped the question at the exclusive Clouds Wine & Guest Estate in Stellenbosch.

Keeping the focus on her dress, Eliza wore her long blonde hair up in a chic knot and decided to enhance her natural beauty with minimal make-up and just a sweep of bronzer

One of the gram, the twins took some photos destined for their social media feeds as they arrived at the event 

Announcing their engagement on Instagram, Greg wrote: ‘So this was the best day of my life. 22nd of July 2020, I asked the love of my life to spend the rest of her life with me and she said YES.

‘Couldn’t be happier and I love you with all my heart @ameliaspencer15.’

In 2021, the couple relocated from South Africa to London shortly after Amelia’s big sister Kitty’s lavish wedding in Rome – with celebrations being spread over four days. 

The couple tied-the-knot at exclusive venue at Quoin Rock Manor House on a mountaintop in the winelands of South Africa’s Western Cape on March 21.

The bride wore a custom Versace dress which took over two-and-a-half months to craft.

Speaking to Hello following their ceremony, Greg said: ‘My love for Amelia has been reborn. Every day I fall more in love with this beautiful human by my side.’
