Princess Kate's Sister-In-Law Alizée Thevenet Shows How French Girl Style Is Done in a Leather Mini, Knee-High Boots and Bold Longchamp Bag
Our take
Alizée Thevenet, Princess Kate’s sister-in-law, consistently embodies a quiet elegance that resonates deeply with the current cultural shift towards understated luxury. Her recent styling choice – a leather mini, knee-high boots, and a statement Longchamp bag – isn’t a dramatic departure, but rather a refinement of the “French girl style” aesthetic that has captivated fashion enthusiasts for years. It’s a look that feels both effortless and intentional, a delicate balance that many struggle to achieve. This isn't about chasing fleeting trends; it's about curating a personal style that feels authentically *you*, a sentiment echoed in the broader fashion landscape, as seen in how Kendall Jenner just gave the Poncho an Unexpected After-Dark Makeover Kendall Jenner Just Gave the Poncho an Unexpected After-Dark Makeover. The resurgence of ballet flats, another subtle yet impactful trend, further reinforces this move away from maximalism and towards timeless pieces that can be styled in myriad ways – Zoë Kravitz is Team Ballerinas Ballet Flats and Jazz Shoes Are Neck and Neck for Fall's Leading Shoe Trend—Zoë Kravitz Is Team Ballerinas.
What makes Thevenet’s look particularly compelling is its accessibility. While royalty often conjures images of extravagant couture, her style feels grounded and relatable. The combination of a simple mini skirt, versatile knee-high boots, and a classic Longchamp bag—a piece known for its practicality and understated chic—demonstrates that achieving a polished aesthetic doesn't require a significant investment or a complicated wardrobe. The "mocha and white is perfect with a pop of green" color palette she employed is a masterclass in quiet sophistication. These aren't bold, attention-grabbing hues, but rather a harmonious blend of neutrals and a single, thoughtfully chosen accent. This approach speaks to a deeper understanding of how color can enhance, rather than overwhelm, an outfit. It's a style that prioritizes quality over quantity, investing in well-made staples that can be mixed and matched to create a variety of looks, a philosophy increasingly valued by a generation seeking conscious consumption and enduring style.
The broader significance of this development lies in its reflection of a larger cultural shift. We're moving away from the ostentatious displays of wealth and status that dominated fashion trends in recent years, and towards a more considered and personal approach to style. This isn't to say that luxury is disappearing, but rather that it’s being redefined. It's no longer about showcasing designer labels, but about cultivating a sense of quiet confidence and refined taste. Alizée Thevenet’s style embodies this new definition of luxury, proving that true elegance lies in simplicity, quality, and a deep understanding of one's own personal aesthetic. The popularity of trends like oyster nails, another subtle expression of personal style Oyster Nails Are Trending and One of the Prettiest Way to Send Off Summer—Here Are 7 Designs to Try, further underscores this desire for understated beauty and self-expression.
Looking ahead, it will be fascinating to observe how this trend of quiet luxury continues to evolve. Will we see more influencers and celebrities embracing this aesthetic, further solidifying its place in the mainstream? Or will it remain a niche style, appreciated by those who value understated elegance above all else? One thing is certain: Alizée Thevenet's influence is undeniable, and her ability to effortlessly embody the essence of French girl style makes her a true style icon for our times – a modern muse demonstrating that true style is not about chasing trends, but about cultivating a timeless sense of self.
Like big sister Pippa Middleton, James Middleton and his wife Alizée Thevenet live a fairly low-key life in the English countryside, but Alizée showed off her early fall style during a rare red carpet appearance in Paris.
Thevenet has been a longtime fan of Longchamp, and she was on hand for the opening of the brand’s art festival, held in the heart of the Marais on September 3. Alizée is known for her funky, vintage-inspired style, often wearing bold prints or quirky trouser suits, and she went with a '70s-esque outfit for the celebration of visual and performing arts.
Princess Kate’s sister-in-law dressed in head-to-toe Longchamp, choosing a mocha croc-print mini skirt with matching knee-high boots and a white bell-sleeved blouse, but it was her bag that stole the show.
Alizée gave her neutral outfit a bright pop of color with Longchamp's Le Pliage Xtra Glossy M Shoulder Bag in a vivid green “Matcha” shade.
While this shade of green might not be the most obvious choice to pair with a deep brown and white look, it was the perfect way to integrate one of summer’s saturated color trends with the more autumnal croc textures of her outfit (not to mention, the glossy bag perfectly matched the event’s step-and-repeat).
The Middleton family has a long history with Longchamp. Princess Kate was pictured carrying the French brand’s Le Pliage bags back in her University of St Andrews days and continues to carry the versatile totes while traveling.
Meanwhile, Alizée and mother-in-law Carole Middleton both leaned into Longchamp at Wimbledon this summer, with Carole carrying two different bags from the French fashion house to this year’s championships.
As for Alizée, she swapped her bold green Le Pliage for a more neutral purse at Wimbledon 2026, carrying a brown Longchamp Épure XS Camera Bag with her ivory Sézane dress for a double dose of French girl fashion.
