This catalogue accompanies the exhibition Art & Fashion in the Calouste Gulbenkian museum, and highlights the inseparable relationship between art and fashion: art finds a constant source of inspiration in fashion, while fashion finds permanence and memory in art. Both disciplines engage in a dialogue around beauty, both ephemeral and eternal, as an invisible thread between past and present. The extraordinary Gulbenkian Collection, with pieces from Ancient Egypt to the 20th century, allows for a unique encounter between masterpieces of painting and decorative arts and iconic haute couture creations. It is not a question of comparison, but of establishing visual and symbolic conversations: contemporary silhouettes alongside Renaissance folds, exquisite embroidery juxtaposed with modernist flashes, ancient iconography reinterpreted. The book captures that moment when the museum is transformed into a living space where art and fashion face each other, reminding us that beauty knows no boundaries, only the passage of time.
