Lady Amelia and Lady Eliza Spencer prove the old adage that style runs in the family. The 32-year-old twin sisters—who are the daughters of Princess Diana’s brother, Charles, and the sisters of Lady Kitty Spencer—have made headlines in recent months for not just their famous last name, but their polished personal style and retro flair. From the duo’s immaculately coordinated black-and-white Cannes gowns to their stellar tennis looks at Wimbledon, the Spencer sisters are emerging as fashion icons in their own right, generating headlines and upholding the legacy of their sartorial forebears.

Naturally, luxury brands have taken note. In June, Aspinal of London tapped the sisters as ambassadors, releasing a swanky ’60s-inspired campaign starring the chic pair. “We are delighted to be partnering with Aspinal as their new brand ambassadors—a collaboration that feels especially meaningful, as we have been wearing and admiring the brand for years,” the sisters tell InStyle. “Their bags have long been our accessory of choice for red-carpet appearances and formal events, with a beautifully crafted design for every occasion.”

The British heritage line known for outfitting everyone from Kate Middleton to Selena Gomez embodies a timeless elegance that “perfectly aligns with our personal style,” the Spencer sisters continue. The recent campaign marks the first extension of an ongoing partnership with their longtime accessory favorite—and don’t worry, there’s more to come.

Ahead, Lady Eliza and Lady Amelia Spencer share their favorite style tips, fashion icons, and how to plan the perfect outfit for Wimbledon in the latest iteration of InStyle‘s How I Get Dressed.

Their “Forever Bags”

“We truly adore every piece Aspinal creates. Their designs embody timeless elegance and classic silhouettes that transcend trends and stay effortlessly stylish through the years. Whether it’s the iconic Mayfair Mini, the practical yet polished London Tote, or the sophisticated Mayfair Clutch, there’s an Aspinal piece for every occasion. These are forever bags—refined, versatile, and made to last.”

Their Accessory for Summer

“Aspinal’s silk scarves are among our absolute favorite pieces from their collection. There is something so effortlessly glamorous about them: timeless, elegant, and endlessly versatile. With Brigitte Bardot and the 1960s as our ultimate fashion inspiration, the recent campaign celebrating that era felt like a dream come true. The styling, the mood, the energy… it was as if it was made just for us. Truly, it was meant to be.”

Their Low-Effort Wardrobe Staples

“Classic jeans, white T-shirts, and comfortable sneakers.”

Their Trick to Elevating Any Outfit

“Yes, accessories! No matter the outfit or occasion, we truly believe accessories are what elevate a look. A beautiful bag, chic sunglasses, or even a silk scarf can transform something simple into something statement. They express personality, tell a story, and instantly make any outfit feel complete and unique.  For us, it’s never just about clothes—it’s how you bring them to life.”

The Fashion Trend They’re Loving Right Now

“Yes, always the ‘60s! We’ve long been inspired by the elegance and effortless glamour of that era, and after working on the Aspinal campaign and its gorgeous 1960s style, we’ve fallen in love with the era all over again. From the structured silhouettes to the feminine touches and iconic accessories, it’s an era that radiates timeless beauty and also the joy of the era!”

How to Plan the Perfect Wimbledon Outfit

“Go for smart tailoring in light tones, as it is ideal for the British summer—chic, refined, and weather-appropriate. Choose breathable fabrics like linen or lightweight cotton, perfect for shifting temperatures.”

“Accessorize with practical elegance, such as classic sunglasses and structured handbags (e.g., Aspinal), striking the right balance between polished and purposeful. Layer for unpredictable weather, as we all know that UK summer weather can be changeable. Having a smart blazer or trench at the ready keeps you stylishly prepared if the sun vanishes.”

“Embrace a look that’s elegant yet effortless; neutral pastels, breathable fabrics, practical accessories, and polished grooming will help you blend timeless style with Wimbledon sophistication.”
