October 1, 1926. In American Vogue a simple black sheath dress is featured for the first time alongside many flamboyant colored garments and lavish embroideries. The Little Black Dress is signed by Coco Chanel and it is praised by the renowned magazine as the garment destined to become "a sort of uniform for women all over the world." With the hindsight of ninety years the words of the American magazine sound like a prophecy. In short order the Little Black Dress becomes the very symbol of Chanel and a "must" in every woman's wardrobe.LBD: a model devoid of particular forms and a color that at once negates and includes all colors. The Little Black Dress is a Little Blackboard on which one can write all the signs of the Fashion Universe. No other woman's garment has had so many different elaborations. Since 1926 the LBD indefatigably brings to the female body an ever-new interpretation in its modes of being and meaning.After Chanel, it was cinema that made the LBD the best-suited costume to express new models of Femininity: Rita Hayworth, Lauren Bacall, Marilyn Monroe…and in 1961, Audrey Hepburn with Breakfast at Tiffany's lends a touch of eternity to this frock!Since then the LBD continues to spark the imagination and creativity of the important Fashion labels: everyone, no matter if young or established, tests their mettle. In France, the fashion houses Chanel and Lanvin, which gave rise to this myth, propose models that break all tradition.In Italy “the Sicilian dress” of Dolce & Gabbana seems to hark back to the ancestral archetypes of the Mediterranean world.In Holland Iris Van Herpen abandons traditional fabrics and for the first time she creates aLittle Black Dress modeled by a 3D printer; Viktor & Rolf use the black dress for their most daring experiments.But in these ninety years the sheath dress is a witness not only of sudden whims of fashion: its success and its moments of oblivion mark the epochal changes of the history of women in the XX century
