Princess Diana's twin nieces, Lady Amelia and Lady Eliza Spencer, showcased their autumnal style at the launch event for luxury designer brand Marc Cain's new Equestrian Grace collection. The event took place on Wednesday at the Four Seasons Hotel in Hampshire.

Lady Eliza Spencer wore a long-sleeved shirt paired with a tweed mini skirt, dark ankle boots, and gold stud earrings. Lady Amelia Spencer opted for a light brown coat over a sleeveless mini dress and heels, completing her look with slicked-back hair and similar earrings. Both sisters are 34 years old.

The Equestrian Grace collection, launched on September 2, aims to blend "heritage codes" with "modern femininity," according to the brand. Behind-the-scenes footage from a photoshoot at the estate described the sisters as "taking fashion to the countryside."

Later that evening, the Spencer sisters attended an outdoor dinner with other guests, including Renee Stewart, daughter of singer Rod Stewart.

This appearance follows Lady Eliza's recent public comments on the return of her cousin, Prince Harry, and Meghan Markle, to the UK. During a launch event for her own rosé, Lala V, on the same day the Duke and Duchess of Sussex arrived in Birmingham, Lady Eliza called her cousin's return "exciting." She told The Mirror that she and her family "would love to be able to find some time to visit." When asked about potentially sharing wine-making insights with Meghan Markle, who launched her rosé last July, Lady Eliza responded with "Maybe."

Lady Eliza and her fiancé, Channing Millerd, also recently launched their £27-a-bottle rosé at a retailer in Knightsbridge. In comparison, Meghan Markle's rosé retails for £22.

Lady Eliza has hinted at wedding plans, sharing photos from a trip to the Amalfi Coast with the caption "Wedding venue hunting begins... @palazzoavino you have completely stolen our hearts." Her swimsuit in the photos was personalized with "Future Mrs M." The couple, who have expressed a desire for a destination wedding, became engaged last July in Santorini. Millerd, an entrepreneur and brand chief operating officer, designed Eliza's engagement ring, a 2.5-carat pear-cut diamond, which reportedly pays tribute to Princess Diana. The couple celebrated their engagement with a party in Cape Town in January.
