Brigitte's style: The message is still ageless and unashamedly sexy
Brigitte Trogneux's style has piqued interest the world over in the past month or so, with her penchant for skinny jeans, sharp tailoring and miniskirts signalling a refreshingly risqué rewriting of the rules of political style.
For her husband Emmanuel Macron's inauguration as French president last Sunday, Trogneux opted for a powder blue dress and jacket by Louis Vuitton, which she accessorised with pale beige high heels and a neatly elegant top handle Capucines bag, also by Louis Vuitton.
Although the cigarette-slim leather trousers and New Balance trainers which Trogneux has worn on the campaign trail suggested a woman who would coin a new spin on political dressing, there were some indicators that she, and Louis Vuitton's artistic director Nicolas Ghesquière, had looked to tradition in their choice of look the really big ceremony.
On social media, immediate comparisons were drawn with the Ralph Lauren skirt suit which Melania Trump wore on Inauguration Day in January which was in turn said to have been inspired by Jackie Kennedy's 1961 look. There were also similarities with Princess Diana in her post-divorce years, when she favoured polished tailoring but with skirts in more daring lengths than she had been able to experiment with as a royal.
The French media has praised Trogneux for her "cool attitude" and "wonderwoman" style. She is also the latest incarnation of the insouciant French look which has become shorthand for aspirational dressing around the world.
Trogneux's take swaps the messy bed hair for a defiantly glossy blow dry and slouchy silhouettes for figure-enhancing cuts, but the message is still ageless and unashamedly - yet modernly - sexy.
It was unsurprising that 64-year-old Trogneux - who will work as an unpaid advisor to her husband, concentrating on education reform - turned to Louis Vuitton for her most important outfit on the public stage to date. After meeting Delphine Arnault - executive vice president of Louis Vuitton - in 2014, Trogneux developed a close relationship with the house which means they now loan her looks for many of her public appearances.
It's a policy which has created some controversy in France, and the moment that her husband entered the Élysée Palace could have marked a turning point for Trogneux. But she has clearly decided that the Vuitton partnership will remain.
Indeed, when it comes to diplomacy and patriotism, Vuitton is the smart choice. As the jewel in the crown of LVMH, one of France's most prestigious and successful business conglomerates, Trogneux's choice of designer projects all the right messages.
Vuitton is also less well-associated with dressing high-profile public figures, with Chanel and Dior having historically held the monopoly in this area.
Chanel's Karl Lagerfeld is said to know the Macron-Trogneuxs and submitted a sketch to fashion website WWD for the inauguration look, so we can no doubt expect to see her wearing the label at some point.
And one can imagine that Maria Grazia Chiuri, Dior's recently installed creative director who has made feminism and women's rights a mainstay of her design message, will have plenty of ideas for dressing a presidential wife with a difference.
