Widely credited with launching the career of Renzo Mongiardino, nonogenarian Italian Countess, Cristiana Brandolini d'Adda, is a tastemaker and fashion icon through and through. Francesca Simpson explores her unique joie de vivre, spectacular homes in Paris and Vistorta, and unfaltering personal style.

Countess Cristiana Brandolini d'Adda is the kind of extraordinary woman for whom life is quite literally art. From how she transforms a space - dressing a room with her unique and deeply personal panache - to how she styles an outfit, her eclectic, signature aesthetic is embued with an inherent joie de vivre and inimitable flair, often copied but never matched. Her almost languid elegance defies conventionality; her unfaltering sense of style, like her quick-witted charm, is embedded deep in her rather illustrious DNA (Fiat heiress Cristiana (nee Agnelli) married the late Brando Brandolini d'Adda, Conte di Valmareno in 1947).

There is a certain tension in her style too: on the one hand, a rebelliousness and desire to challenge the status quo; on the other, an old-fashioned deep-seated sense of duty and loyalty. This shines forth through her unswerving devotion to her family, as a wife, mother to four sons, grandmother, great grandmother, and ultimately matriarch, to the extended Brandolini clan. The manner in which Cristiana perceives and moves through the world reflects this duality: her understated elegance the perfect foil to her unreserved passion and lively unpredictability, which has characterised her personal sense of style for so long.

Her granddaughter, fashion designer Coco Brandolini, draws attention to Cristiana's "unorthodox eye and ability to see beauty in the seemingly mundane", as well as her desire to meld worlds, seamlessly bridging the glamour of high society with the warmth and comfort of conventional family life. Equally happy in haute couture or flea market finds, Cristiana's untrammelled appreciation of beauty gives her free reign to indulge and celebrate her highly individual, and at times eccentric, sense of personal taste.

Speaking to Cabana earlier this year, Coco described joining her grandmother when she was getting ready. "In amongst the bamboo furniture, she had all these bags hanging on the mirror and now I do the same. My grandmother remains my biggest inspiration. As someone who's met everyone and seen it all, [she] never criticizes the younger generation. Open-minded, she always sees something interesting."

If Cristiana's wardrobe bares testament to her originality, so too do her principal residences: a 15^th century palazzo overlooking Venice's Grand Canal; a hotel particulier in Paris and - in some senses, the jewel in the crown - the family's charmingly bucolic estate, Vistorta. The latter, at the foothills of the Alps, is captured in Cabana Issue 18 (launching 10 October). Truly a people person, Cristiana's homes represent her unflinching generosity of spirit and an innate ability to discover and nurture talent in those around her.

After all, her residences are collaborative projects. Her willingness to work with, and give free rein to, the imagination of her collaborators blossomed into an array of magnificent, yet very livable, homes. With this approach, Cristiana launched the stellar career of, among others, Renzo Mongiardino, and gave fresh impetus to the English garden designer, Russell Page, who would produce some of his best work for her. The enduring allure of her homes - as the latest issue of Cabana bears witness to - is testament to her confidence in their abilities and creative strength in realising and remaining faithful to her vision.
